DESCRIPTION  
The TPS6204x family of devices are high efficiency  
synchronous step-down dc-dc converters optimized for  
battery powered portable applications. The devices are  
ideal for portable applications powered by a single Li-Ion  
battery cell or by 3-cell NiMH/NiCd batteries. With an  
output voltage range from 6.0 V down to 0.7 V, the devices  
support low voltage DSPs and processors in PDAs,  
pocket PCs, as well as notebooks and subnotebook  
computers. The TPS6204x operates at a fixed switching  
frequency of 1.25 MHz and enters the power save mode  
operation at light load currents to maintain high efficiency  
over the entire load current range. For low noise  
applications, the devices can be forced into fixed  
frequency PWM mode by pulling the MODE pin high. The  
TPS6204x supports up to 1.2-A load current.

The TPS6204x is a synchronous step-down converter operating with typically 1.25 MHz fixed frequency. At moderate  
to heavy load currents, the device operates in pulse width modulation (PWM), and at light load currents, the device  
enters power save mode operation using pulse frequency modulation (PFM). When operating in PWM mode, the  
typical switching frequency is 1.25 MHz with a minimum switching frequency of 1 MHz. This makes the device  
suitable for xDSL applications minimizing RF (radio frequency) interference.  
During PWM operation the converter uses a unique fast response voltage mode controller scheme with input voltage  
feedforward to achieve good line and load regulation, allowing the use of small ceramic input and output capacitors.  
At the beginning of each clock cycle initiated by the clock signal (S) the P-channel MOSFET switch turns on and the  
inductor current ramps up until the comparator trips and the control logic turns off the switch. The current limit  
comparator also turns off the switch in case the current limit of the P-channel switch is exceeded. After the dead time  
preventing current shoot through, the N-channel MOSFET rectifier is turned on and the inductor current ramps down.  
The next cycle is initiated by the clock signal, again turning off the N-channel rectifier and turning on the P-channel  
switch.  
The Gm amplifier as well as the input voltage determines the rise time of the saw tooth generator, and therefore, any  
change in input voltage or output voltage directly controls the duty cycle of the converter, giving a very good line and  
load transient regulation.  
POWER SAVE MODE OPERATION  
As the load current decreases, the converter enters power save mode operation. During power save mode the  
converter operates with reduced switching frequency in PFM mode and with a minimum quiescent current  
maintaining high efficiency.  
The converter monitors the average inductor current and the device enters power save mode when the average  
inductor current is below the threshold. The transition point between PWM and power save mode is given by the  
transition current with the following equation:  
V
I
18.66 W  
I
+
transition  
(1)  
During power save mode the output voltage is monitored with the comparator by the threshold’s comp low and comp  
high. As the output voltage falls below the comp low threshold set to typically 0.8% above the nominal output voltage,  
the P-channel switch turns on. The P-channel switch remains on until the transition current (1) is reached. Then the  
N-channel switch turns on completing the first cycle. The converter continues to switch with its normal duty cycle  
determined by the input and output voltage but with half the nominal switching frequency of 625-kHz typ. Thus the  
output voltage rises and as soon as the output voltage reaches the comp high threshold of 1.6%, the converter stops  
switching. Depending on the load current, the converter switches for a longer or shorter period of time in order to  
deliver the energy to the output. If the load current increases and the output voltage can not be maintained with the  
transition current , equation (1), the converter enters PWM again. See Figure 11 and Figure 12 under the typical  
graphs section and Figure 14 for power save mode operation. Among other techniques this advanced power save  
mode method allows high efficiency over the entire load current range and a small output ripple of typically 1% of  
the nominal output voltage.  
Setting the power save mode thresholds to typically 0.8% and 1.6% above the nominal output voltage at light load  
current results in a dynamic voltage positioning achieving lower absolute voltage drops during heavy load transient  
changes. This allows the converter to operate with small output capacitors like 22 µF and still having a low absolute  
voltage drop during heavy load transient. Refer to Figure 14 as well for detailed operation of the power save mode.

The converter enters the fixed frequency PWM mode as soon as the output voltage falls below the comp low 2

DYNAMIC VOLTAGE POSITIONING  
As described in the power save mode operation sections before and as detailed in Figure 14 the output voltage is  
typically 0.8% (i.e., 1% on average) above the nominal output voltage at light load currents, as the device is in power  
save mode. This gives additional headroom for the voltage drop during a load transient from light load to full load.  
In the other direction during a load transient from full load to light load the voltage overshoot is also minimized by  
turning on the N-Channel rectifier switch to pull the output voltage actively down.  
MODE (AUTOMATIC PWM/PFM OPERATION AND FORCED PWM OPERATION)  
Connecting the MODE pin to GND enables the automatic PWM and power save mode operation. The converter  
operates in fixed frequency PWM mode at moderate to heavy loads and in the PFM mode during light loads,  
maintaining high efficiency over a wide load current range.  
Pulling the MODE pin high forces the converter to operate constantly in the PWM mode even at light load currents.  
The advantage is the converter operates with a fixed switching frequency that allows simple filtering of the switching  
frequency for noise sensitive applications. In this mode, the efficiency is lower compared to the power save mode  
during light loads (see Figure 1 to Figure 3). For additional flexibility it is possible to switch from power save mode  
to forced PWM mode during operation. This allows efficient power management by adjusting the operation of the  
TPS6204x to the specific system requirements.  
100% DUTY CYCLE LOW DROPOUT OPERATION  
The TPS6204x offers a low input to output voltage difference while still maintaining regulation with the use of the 100%  
duty cycle mode. In this mode, the PChannel switch is constantly turned on. This is particularly useful in battery  
powered applications to achieve longest operation time by taking full advantage of the whole battery voltage range.  
i.e. The minimum input voltage to maintain regulation depends on the load current and output voltage and can be

SOFTSTART  
The TPS6204x series has an internal softstart circuit that limits the inrush current during start up. This prevents  
possible voltage drops of the input voltage in case a battery or a high impedance power source is connected to the  
input of the TPS6204x.  
The softstart is implemented with a digital circuit increasing the switch current in steps of typically I /8, I /4, I /2  
LIM  
LIM  
LIM  
and then the typical switch current limit 1.85 A as specified in the electrical parameter table. The start-up time mainly  
depends on the output capacitor and load current, see Figure 13.  
SHORT-CIRCUIT PROTECTION  
As soon as the output voltage falls below 50% of the nominal output voltage, the converter switching frequency as  
well as the current limit is reduced to 50% of the nominal value. Since the short-circuit protection is enabled during  
start-up, the device does not deliver more than half of its nominal current limit until the output voltage exceeds 50%  
of the nominal output voltage. This needs to be considered in case a load acting as a current sink is connected to  
the output of the converter.  
THERMAL SHUTDOWN  
As soon as the junction temperature of typically 150_C is exceeded the device goes into thermal shutdown. In this  
mode, the P-Channel switch and N-Channel rectifier are turned off. The device continues its operation when the  
junction temperature falls below typically 150°C again.  
ENABLE  
Pulling the EN low forces the part into shutdown mode, with a shutdown current of typically 0.1 µA. In this mode, the  
P-Channel switch and N-Channel rectifier are turned off and the whole device is in shut down. If an output voltage  
is present during shut down, which could be an external voltage source or super cap, the reverse leakage current  
is specified under electrical parameter table. For proper operation the enable (EN) pin must be terminated and should  
not be left floating.  
Pulling EN high starts up the TPS6204x with the softstart as described under the section Softstart.  
UNDERVOLTAGE LOCKOUT  
The undervoltage lockout circuit prevents device misoperation at low input voltages. It prevents the converter from  
turning on the switch or rectifier MOSFET with undefined conditions.

APPLICATION INFORMATION  
ADJUSTABLE OUTPUT VOLTAGE VERSION  
When the adjustable output voltage version TPS62040 is used, the output voltage is set by the external resistor  
divider. See Figure 15.  
The output voltage is calculated as:  
R1  
+ 0.5 V   ǒ1 ) Ǔ  
V
O
R2  
(3)  
with R1 + R2 1 Mand internal reference voltage V typical = 0.5 V  
ref  
R1 + R2 should not be greater than 1 Mbecause of stability reasons. To keep the operating quiescent current to  
a minimum, the feedback resistor divider should have high impedance with R1+R21 M. Due to this and the low  
reference voltage of V = 0.5 V, the noise on the feedback pin (FB) needs to be minimized. Using a capacitive divider  
ref  
C1 and C2 across the feedback resistors minimizes the noise at the feedback, without degrading the line or load  
transient performance.  
C1 and C2 should be selected as:  
1
C1 +  
2   p   10 kHz   R1  
(4)  
with:  
R1 = upper resistor of voltage divider  
C1 = upper capacitor of voltage divider  
For C1 a value should be chosen that comes closest to the calculated result.  
R1  
R2  
C2 +  
  C1  
(5)  
with:  
R2 = lower resistor of voltage divider  
C2 = lower capacitor of voltage divider  
For C2, the selected capacitor value should always be selected larger than the calculated result. For example, in  
Figure 15 for C2 100 pF are selected for a calculated result of C2 = 88.42 pF.  
If quiescent current is not a key design parameter C1 and C2 can be omitted, and a low impedance feedback divider  
has to be used with R1 + R2 < 100 k. This reduces the noise available on the feedback pin (FB) as well but increases  
the overall quiescent current during operation. The higher the programmed output voltage the lower the feedback  
impedance has to be for best operation when not using C1 and C2.

Inductor Selection  
The TPS6204x typically uses a 6.2-µH output inductor. Larger or smaller inductor values can be used to optimize  
the performance of the device for specific operation conditions. The selected inductor has to be rated for its dc  
resistance and saturation current. The dc resistance of the inductance directly influences the efficiency of the  
converter. Therefore an inductor with the lowest dc resistance should be selected for highest efficiency.  
Formula (7) calculates the maximum inductor current under static load conditions. The saturation current of the  
inductor should be rated higher than the maximum inductor current as calculated with formula (7). This is needed  
because during heavy load transient the inductor current rises above the value calculated under (7).

Open core inductors have a soft saturation characteristic and they can usually handle higher inductor currents versus  
a comparable shielded inductor. A more conservative approach is to select the inductor current rating just for the  
maximum switch current of 2.2 A for the TPS6204x. Keep in mind that the core material from inductor to inductor  
differs and has an impact on the efficiency, especially at high switching frequencies. Refer to Table 1 and the typical  
applications and inductors selection.

Output Capacitor Selection  
The advanced fast response voltage mode control scheme of the TPS6204x allows the use of small ceramic  
capacitors with a typical value of 22 µF without having large output voltage under and overshoots during heavy load  
transients. Ceramic capacitors having low ESR values have the lowest output voltage ripple and are recommended.  
If required, tantalum capacitors may also be used. Refer to Table 2 for component selection.  
If ceramic output capacitor are used, the capacitor RMS ripple current rating always meets the application  
requirements. Just for completeness the RMS ripple current is calculated as:

At light load currents, the device operates in power save mode and the output voltage ripple is independent of the  
output capacitor value. The output voltage ripple is set by the internal comparator thresholds. The typical output  
voltage ripple is 1% of the nominal output voltage.  
Input Capacitor Selection  
Because of the nature of the buck converter having a pulsating input current, a low ESR input capacitor is required  
for best input voltage filtering and minimizing the interference with other circuits caused by high input voltage spikes.  
The input capacitor should have a minimum value of 22 µF. The input capacitor can be increased without any limit  
for better input voltage filtering.

Layout Considerations  
For all switching power supplies, the layout is an important step in the design especially at high peak currents and  
switching frequencies. If the layout is not carefully done, the regulator might show stability problems as well as EMI  
problems. Therefore, use wide and short traces for the main current paths as indicated in bold in Figure 16. These  
traces should be routed first. The input capacitor should be placed as close as possible to the IC pins as well as the  
inductor and output capacitor. The feedback resistor network should be routed away from the inductor and switch  
node to minimize noise and magnetic interference. To further minimize noise from coupling into the feedback network  
and feedback pin, the ground plane or ground traces should be used for shielding. A common ground plane or a star  
ground as shown below should be used. This becomes very important especially at high switching frequencies of  
1.25 MHz.

THERMAL INFORMATION  
One of the most influential components on the thermal performance of a package is board design. In order to take  
full advantage of the heat dissipating abilities of the PowerPADt packages, a board should be used that acts similar  
to a heat sink and allows for the use of the exposed (and solderable), deep downset pad. For further information  
please refer to Texas Instruments application note (SLMA002) PowerPAD Thermally Enhanced Package.  
The PowerPADt of the 10-pin MSOP package has an area of 1,52 mm × 1,79 mm ( 0,05 mm) and must be soldered  
to the PCB to lower the thermal resistance. Thermal vias to the next layer further reduce the thermal resistance.

Pb-Free (RoHS): TI's terms "Lead-Free" or "Pb-Free" mean semiconductor products that are compatible with the current RoHS requirements for all 6 substances, including the requirement that  
lead not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, TI Pb-Free products are suitable for use in specified lead-free processes.  
Pb-Free (RoHS Exempt): This component has a RoHS exemption for either 1) lead-based flip-chip solder bumps used between the die and package, or 2) lead-based die adhesive used between  
the die and leadframe. The component is otherwise considered Pb-Free (RoHS compatible) as defined above.  
Green (RoHS & no Sb/Br): TI defines "Green" to mean Pb-Free (RoHS compatible), and free of Bromine (Br) and Antimony (Sb) based flame retardants (Br or Sb do not exceed 0.1% by weight  
in homogeneous material)  
(3) MSL, Peak Temp. -- The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.

IMPORTANT NOTICE  
Texas Instruments Incorporated and its subsidiaries (TI) reserve the right to make corrections, enhancements, improvements and other  
changes to its semiconductor products and services per JESD46C and to discontinue any product or service per JESD48B. Buyers should  
obtain the latest relevant information before placing orders and should verify that such information is current and complete. All  
semiconductor products (also referred to herein as “components”) are sold subject to TI’s terms and conditions of sale supplied at the time  
of order acknowledgment.  
TI warrants performance of its components to the specifications applicable at the time of sale, in accordance with the warranty in TI’s terms  
and conditions of sale of semiconductor products. Testing and other quality control techniques are used to the extent TI deems necessary  
to support this warranty. Except where mandated by applicable law, testing of all parameters of each component is not necessarily  
performed.  
TI assumes no liability for applications assistance or the design of Buyers’ products. Buyers are responsible for their products and  
applications using TI components. To minimize the risks associated with Buyers’ products and applications, Buyers should provide  
adequate design and operating safeguards.  
TI does not warrant or represent that any license, either express or implied, is granted under any patent right, copyright, mask work right, or  
other intellectual property right relating to any combination, machine, or process in which TI components or services are used. Information  
published by TI regarding third-party products or services does not constitute a license to use such products or services or a warranty or  
endorsement thereof. Use of such information may require a license from a third party under the patents or other intellectual property of the  
third party, or a license from TI under the patents or other intellectual property of TI.  
Reproduction of significant portions of TI information in TI data books or data sheets is permissible only if reproduction is without alteration  
and is accompanied by all associated warranties, conditions, limitations, and notices. TI is not responsible or liable for such altered  
documentation. Information of third parties may be subject to additional restrictions.  
Resale of TI components or services with statements different from or beyond the parameters stated by TI for that component or service  
voids all express and any implied warranties for the associated TI component or service and is an unfair and deceptive business practice.  
TI is not responsible or liable for any such statements.  
Buyer acknowledges and agrees that it is solely responsible for compliance with all legal, regulatory and safety-related requirements  
concerning its products, and any use of TI components in its applications, notwithstanding any applications-related information or support  
that may be provided by TI. Buyer represents and agrees that it has all the necessary expertise to create and implement safeguards which  
anticipate dangerous consequences of failures, monitor failures and their consequences, lessen the likelihood of failures that might cause  
harm and take appropriate remedial actions. Buyer will fully indemnify TI and its representatives against any damages arising out of the use  
of any TI components in safety-critical applications.  
In some cases, TI components may be promoted specifically to facilitate safety-related applications. With such components, TI’s goal is to  
help enable customers to design and create their own end-product solutions that meet applicable functional safety standards and  
requirements. Nonetheless, such components are subject to these terms.  
No TI components are authorized for use in FDA Class III (or similar life-critical medical equipment) unless authorized officers of the parties  
have executed a special agreement specifically governing such use.  
Only those TI components which TI has specifically designated as military grade or “enhanced plastic” are designed and intended for use in  
military/aerospace applications or environments. Buyer acknowledges and agrees that any military or aerospace use of TI components  
which have not been so designated is solely at the Buyer's risk, and that Buyer is solely responsible for compliance with all legal and  
regulatory requirements in connection with such use.  
TI has specifically designated certain components which meet ISO/TS16949 requirements, mainly for automotive use. Components which  
have not been so designated are neither designed nor intended for automotive use; and TI will not be responsible for any failure of such  
components to meet such requirements.
