7 Detailed Description  
7.1 Overview  
The TPS562201 and TPS562208 are 2-A synchronous step-down converters. The proprietary D-CAP2 mode  
control supports low-ESR output capacitors, such as specialty polymer capacitors and multi-layer ceramic  
capacitors, without complex external compensation circuits. The fast transient response of D-CAP2 mode control  
can reduce the output capacitance required to meet a specific level of performance.

7.3 Feature Description  
7.3.1 Adaptive On-Time Control and PWM Operation  
The main control loop of the TPS562201 is adaptive on-time pulse width modulation (PWM) controller that  
supports a proprietary D-CAP2 mode control. The D-CAP2 mode control combines adaptive on-time control with  
an internal compensation circuit for pseudo-fixed frequency and low external component count configuration with  
both low ESR and ceramic output capacitors. It is stable even with virtually no ripple at the output.  
At the beginning of each cycle, the high-side MOSFET is turned on. This MOSFET is turned off after internal one  
shot timer expires. This one shot duration is set proportional to the converter input voltage, VIN, and inversely  
proportional to the output voltage, VO, to maintain a pseudo-fixed frequency over the input voltage range, hence  
it is called adaptive on-time control. The one-shot timer is reset and the high-side MOSFET is turned on again  
when the feedback voltage falls below the reference voltage. An internal ramp is added to reference voltage to  
simulate output ripple, eliminating the need for ESR induced output ripple from D-CAP2 mode control.  
7.3.2 Pulse Skip Control (TPS562201)  
The TPS562201 and TPS562208 are designed with Advanced Eco-mode to maintain high light load efficiency.  
As the output current decreases from heavy load condition, the inductor current is also reduced and eventually

comes to point that its rippled valley touches zero level, which is the boundary between continuous conduction  
and discontinuous conduction modes. The rectifying MOSFET is turned off when the zero inductor current is  
detected. As the load current further decreases, the converter runs into discontinuous conduction mode. The on-  
time is kept almost the same as it was in the continuous conduction mode so that it takes longer time to  
discharge the output capacitor with smaller load current to the level of the reference voltage. This makes the  
switching frequency lower, proportional to the load current, and keeps the light load efficiency high. The  
transition point to the light load operation IOUT(LL) current can be calculated in 方程式 1.

7.3.3 Soft Start and Pre-Biased Soft Start  
The TPS562201 and TPS562208 have an internal 1.0-ms soft start. When the EN pin becomes high, the internal  
soft-start function begins ramping up the reference voltage to the PWM comparator. If the output capacitor is pre-  
biased at start-up, the devices initiate switching and start ramping up only after the internal reference voltage  
becomes greater than the feedback voltage, VFB. This scheme ensures that the converters ramp up smoothly  
into regulation point.  
7.3.4 Current Protection  
The output overcurrent limit (OCL) is implemented using a cycle-by-cycle valley detect control circuit. The switch  
current is monitored during the OFF state by measuring the low-side FET drain to source voltage. This voltage is  
proportional to the switch current. To improve accuracy, the voltage sensing is temperature compensated.  
During the on-time of the high-side FET switch, the switch current increases at a linear rate determined by Vin,  
Vout, the on-time, and the output inductor value. During the on-time of the low-side FET switch, this current  
decreases linearly. The average value of the switch current is the load current, Iout. If the monitored current is  
above the OCL level, the converter keeps the low-side FET on and delays the creation of a new set pulse, even  
the voltage feedback loop requires one, until the current level becomes OCL level or lower. In subsequent  
switching cycles, the on-time is set to a fixed value and the current is monitored in the same manner.  
There are some important considerations for this type of over-current protection. The load current is higher than  
the overcurrent threshold by one half of the peak-to-peak inductor ripple current. Also, when the current is being  
limited, the output voltage tends to fall as the demanded load current can be higher than the current available  
from the converter. This can cause the output voltage to fall. When the VFB voltage falls below the UVP  
threshold voltage, the UVP comparator detects it, then the device will shut down after the UVP delay time  
(typically 24 µs) and restart after the hiccup time (typically 15 ms).  
When the overcurrent condition is removed, the output voltage returns to the regulated value.  
7.3.5 Undervoltage Lockout (UVLO) Protection  
UVLO protection monitors the internal regulator voltage. When the voltage is lower than UVLO threshold voltage,  
the device is shut off. This protection is non-latching.  
7.3.6 Thermal Shutdown  
The device monitors the temperature of itself. If the temperature exceeds the threshold value (typically 160°C),  
the device is shut off. This is a non-latch protection.  
7.4 Device Functional Modes  
7.4.1 Normal Operation  
When the input voltage is above the UVLO threshold and the EN voltage is above the enable threshold, the  
TPS562200 can operate in their normal switching modes. Normal continuous conduction mode (CCM) occurs  
when the minimum switch current is above 0 A. In CCM, the TPS562208 operates at a quasi-fixed frequency of  
580 kHz.

7.4.2 Eco-mode Operation  
When the TPS562201 and TPS562208 are in the normal CCM operating mode and the switch current falls to 0  
A, the TPS562200 begins operating in pulse skipping Eco-mode. Each switching cycle is followed by a period of  
energy saving sleep time. The sleep time ends when the VFB voltage falls below the Eco-mode threshold  
voltage. As the output current decreases, the perceived time between switching pulses increases.  
7.4.3 Standby Operation  
When the TPS562201 and TPS562208 are operating in either normal CCM or Eco-mode, they can be placed in  
standby by asserting the EN pin low.

8.2.2 Detailed Design Procedure  
8.2.2.1 Output Voltage Resistors Selection  
The output voltage is set with a resistor divider from the output node to the VFB pin. TI recommends to use 1%  
tolerance or better divider resistors. Start by using 方程式 2 to calculate VOUT.  
To improve efficiency at very light loads, consider using larger value resistors. Too high of resistance will be more  
susceptible to noise and voltage errors from the VFB input current will be more noticeable.

8.2.2.2 Output Filter Selection  
The LC filter used as the output filter has double pole at:  
1
F =  
P
2p LOUT ´ COUT  
(3)  
At low frequencies, the overall loop gain is set by the output set-point resistor divider network and the internal  
gain of the device. The low frequency phase is 180 degrees. At the output filter pole frequency, the gain rolls off  
at a 40 dB per decade rate and the phase drops rapidly. D-CAP2 introduces a high frequency zero that  
reduces the gain roll off to 20 dB per decade and increases the phase to 90 degrees one decade above the  
zero frequency. The inductor and capacitor for the output filter must be selected so that the double pole of  
Equation 3 is located below the high frequency zero but close enough that the phase boost provided be the high  
frequency zero provides adequate phase margin for a stable circuit. To meet this requirement use the values  
recommended in 8-2.

The inductor peak-to-peak ripple current, peak current, and RMS current are calculated using 方程式 4, 方程式  
5, and 方程式 6. The inductor saturation current rating must be greater than the calculated peak current and the  
RMS or heating current rating must be greater than the calculated RMS current.  
Use 580 kHz for fSW. Make sure the chosen inductor is rated for the peak current of 方程式 5 and the RMS

For this design example, the calculated peak current is 3.5 A and the calculated RMS current is 3.01 A. The  
inductor used is a WE 744311330 with a peak current rating of 11 A and an RMS current rating of 6.5 A.  
The capacitor value and ESR determines the amount of output voltage ripple. The TPS562201 and TPS562208  
are intended for use with ceramic or other low-ESR capacitors. Recommended values range from 20 µF to 68  
µF. Use 方程式 7 to determine the required RMS current rating for the output capacitor.

For this design, two TDK C3216X5R0J226M 22-µF output capacitors are used. The typical ESR is 2 mΩ each.  
The calculated RMS current is 0.286 A and each output capacitor is rated for 4 A.  
8.2.2.3 Input Capacitor Selection  
The TPS562201 and TPS562208 require an input decoupling capacitor and a bulk capacitor is needed  
depending on the application. TI recommends a ceramic capacitor over 10 µF for the decoupling capacitor. An  
additional 0.1-µF capacitor (C3) from pin 3 to ground is optional to provide additional high frequency filtering.  
The capacitor voltage rating needs to be greater than the maximum input voltage.  
8.2.2.4 Bootstrap Capacitor Selection  
A 0.1-µF ceramic capacitor must be connected between the VBST to SW pin for proper operation. TI  
recommends to use a ceramic capacitor.

9 Power Supply Recommendations  
The TPS562201 and TPS562208 are designed to operate from input supply voltage in the range of 4.5 V to 17  
V. Buck converters require the input voltage to be higher than the output voltage for proper operation. The  
maximum recommended operating duty cycle is 75%. Using that criteria, the minimum recommended input  
voltage is VO / 0.75.  
10 Layout  
10.1 Layout Guidelines  
1. VIN and GND traces should be as wide as possible to reduce trace impedance. The wide areas are also of  
advantage from the view point of heat dissipation.  
2. The input capacitor and output capacitor should be placed as close to the device as possible to minimize  
trace impedance.  
3. Provide sufficient vias for the input capacitor and output capacitor.  
4. Keep the SW trace as physically short and wide as practical to minimize radiated emissions.  
5. Do not allow switching current to flow under the device.  
6. A separate VOUT path should be connected to the upper feedback resistor.  
7. Make a Kelvin connection to the GND pin for the feedback path.  
8. Voltage feedback loop should be placed away from the high-voltage switching trace, and preferably has  
ground shield.  
9. The trace of the VFB node should be as small as possible to avoid noise coupling.  
10.The GND trace between the output capacitor and the GND pin should be as wide as possible to minimize its  
trace impedance.

11.4 Electrostatic Discharge Caution  
This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled  
with appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.  
ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may  
be more susceptible to damage because very small parametric changes could cause the device not to meet its published  
specifications.

(1) The marketing status values are defined as follows:  
ACTIVE: Product device recommended for new designs.  
LIFEBUY: TI has announced that the device will be discontinued, and a lifetime-buy period is in effect.  
NRND: Not recommended for new designs. Device is in production to support existing customers, but TI does not recommend using this part in a new design.  
PREVIEW: Device has been announced but is not in production. Samples may or may not be available.  
OBSOLETE: TI has discontinued the production of the device.  
(2) RoHS: TI defines "RoHS" to mean semiconductor products that are compliant with the current EU RoHS requirements for all 10 RoHS substances, including the requirement that RoHS substance  
do not exceed 0.1% by weight in homogeneous materials. Where designed to be soldered at high temperatures, "RoHS" products are suitable for use in specified lead-free processes. TI may  
reference these types of products as "Pb-Free".  
RoHS Exempt: TI defines "RoHS Exempt" to mean products that contain lead but are compliant with EU RoHS pursuant to a specific EU RoHS exemption.  
Green: TI defines "Green" to mean the content of Chlorine (Cl) and Bromine (Br) based flame retardants meet JS709B low halogen requirements of <=1000ppm threshold. Antimony trioxide based  
flame retardants must also meet the <=1000ppm threshold requirement.  
(3) MSL, Peak Temp. - The Moisture Sensitivity Level rating according to the JEDEC industry standard classifications, and peak solder temperature.  
(4) There may be additional marking, which relates to the logo, the lot trace code information, or the environmental category on the device.  
(5) Multiple Device Markings will be inside parentheses. Only one Device Marking contained in parentheses and separated by a "~" will appear on a device. If a line is indented then it is a continuation  
of the previous line and the two combined represent the entire Device Marking for that device.  
(6)  
Lead finish/Ball material - Orderable Devices may have multiple material finish options. Finish options are separated by a vertical ruled line. Lead finish/Ball material values may wrap to two  
lines if the finish value exceeds the maximum column width.
