As members of the SWIFT family of dc/dc regulators, the  
TPS54311, TPS54312, TPS54313, TPS54314,  
TPS54315 and TPS54316 low-input-voltage high-output-  
current synchronous-buck PWM converters integrate all  
required active components. Included on the substrate  
with the listed features are a true, high performance,  
voltage error amplifier that provides high performance  
under transient conditions; an undervoltage-lockout circuit  
to prevent start-up until the input voltage reaches 3 V; an  
internally and externally set slow-start circuit to limit  
in-rush currents; and a power good output useful for  
processor/logic reset, fault signaling, and supply  
sequencing.

APPLICATION INFORMATION  
Figure 10 shows the schematic diagram for a typical  
TPS54314 application. The TPS54314 (U1) can provide  
up to 3 A of output current at a nominal output voltage of  
1.8 V. For proper thermal performance, the PowerPAD  
underneath the TPS54314 integrated circuit needs to be  
soldered to the printed circuit board.

The output filter components work with the internal  
compensation network to provide a stable closed loop  
response for the converter.  
INPUT VOLTAGE  
The input to the circuit is a nominal 5 VDC, applied at J1.  
The optional input filter (C2) is a 220-µF POSCAP  
capacitor, with a maximum allowable ripple current of 3 A.  
C8 is the decoupling capacitor for the TPS54314 and must  
be located as close to the device as possible.

TPS5431116.

The VIN pins should be connected together on the printed  
circuit board (PCB) and bypassed with a low ESR ceramic  
bypass capacitor. Care should be taken to minimize the  
loop area formed by the bypass capacitor connections, the  
VIN pins, and the TPS5431116 ground pins. The  
minimum recommended bypass capacitance is 10-µF  
ceramic with a X5R or X7R dielectric and the optimum  
placement is closest to the VIN pins and the PGND pins.  
The output voltage of the converter is fed directly into the  
VSENSE pin of the TPS54314. The TPS54314 is  
internally compensated to provide stability of the output  
under varying line and load conditions.  
OPERATING FREQUENCY  
In the application circuit, a 700 kHz operating frequency is  
selected by leaving FSEL open and connecting a 71.5 kΩ  
resistor between the RT pin and AGND. Different  
operating frequencies may be selected by varying the  
value of R3 using equation 1:  
The TPS5431116 has two internal grounds (analog and  
power). Inside the TPS5431116, the analog ground ties  
to all of the noise sensitive signals, while the power ground  
ties to the noisier power signals. Noise injected between  
the two grounds can degrade the performance of the  
TPS5431116, particularly at higher output currents.  
Ground noise on an analog ground plane can also cause  
problems with some of the control and bias signals. For  
these reasons, separate analog and power ground traces  
are recommended. There should be an area of ground one  
the top layer directly under the IC, with an exposed area for  
connection to the PowerPAD. Use vias to connect this  
ground area to any internal ground planes. Use additional  
vias at the ground side of the input and output filter  
capacitors as well. The AGND and PGND pins should be  
tied to the PCB ground by connecting them to the ground  
area under the device as shown. The only components

Alternately, preset operating frequencies of 350 kHz or  
550 kHz my be selected by leaving RT open and  
connecting the FSEL pin to AGND or VIN respectively.  
OUTPUT FILTER  
The output filter is composed of a 5.2-µH inductor and  
470-µF capacitor. The inductor is a low dc resistance  
(16-m) type, Sumida CDRH104R5R2. The capacitor  
used is a 4-V POSCAP with a maximum ESR of 40 m.

that should tie directly to the power ground plane are the  
input capacitors, the output capacitors, the input voltage  
decoupling capacitor, and the PGND pins of the  
TPS5431116. Use a separate wide trace for the analog  
ground signal path. This analog ground should be used for  
the timing resistor RT, slow-start capacitor and bias  
capacitor grounds. Connect this trace directly to AGND  
(pin 1).  
Connect the output filter capacitor(s) as shown between  
the VOUT trace and PGND. It is important to keep the loop  
formed by the PH pins, Lout, Cout and PGND as small as  
practical.  
Connect the output of the circuit directly to the VSENSE  
pin. Do not place this trace too close to the PH trace. Do  
to the size of the IC package and the device pinout, they  
will have to be routed somewhat close, but maintain as  
much separation as possible while still keeping the layout  
compact.  
The PH pins should be tied together and routed to the  
output inductor. Since the PH connection is the switching  
node, inductor should be located very close to the PH pins  
and the area of the PCB conductor minimized to prevent  
excessive capacitive coupling.  
Connect the bias capacitor from the VBIAS pin to analog  
ground using the isolated analog ground trace. If a  
slow-start capacitor or RT resistor is used, or if the SYNC  
pin is used to select 350-kHz operating frequency, connect  
them to this trace as well.  
Connect the boot capacitor between the phase node and  
the BOOT pin as shown. Keep the boot capacitor close to  
the IC and minimize the conductor trace lengths.

any area available should be used when 3 A or greater  
operation is desired. Connection from the exposed area of  
the PowerPAD to the analog ground plane layer should be  
made using 0.013 inch diameter vias to avoid solder  
wicking through the vias. Six vias should be in the  
PowerPAD area with four additional vias located under the  
device package. The size of the vias under the package,  
but not in the exposed thermal pad area, can be increased  
to 0.018. Additional vias beyond the ten recommended  
that enhance thermal performance should be included in  
areas not under the device package.  
LAYOUT CONSIDERATIONS FOR THERMAL  
PERFORMANCE  
For operation at full rated load current, the analog ground  
plane must provide adequate heat dissipating area. A 3  
inch by 3 inch plane of 1 ounce copper is recommended,  
though not mandatory, depending on ambient temperature  
and airflow. Most applications have larger areas of internal  
ground plane available, and the PowerPAD should be  
connected to the largest area available. Additional areas  
on the top or bottom layers also help dissipate heat, and

The actual slow-start is likely to be less than the above  
approximation due to the brief ramp-up at the internal rate.  
DETAILED DESCRIPTION  
Under Voltage Lock Out (UVLO)  
VBIAS Regulator (VBIAS)  
The TPS54311 16 incorporates an under voltage lockout  
circuit to keep the device disabled when the input voltage  
(VIN) is insufficient. During power up, internal circuits are  
held inactive until VIN exceeds the nominal UVLO  
threshold voltage of 2.95 V. Once the UVLO start threshold  
is reached, device start-up begins. The device operates  
until VIN falls below the nominal UVLO stop threshold of  
2.8 V. Hysteresis in the UVLO comparator, and a 2.5-µs  
rising and falling edge deglitch circuit reduce the likelihood  
of shutting the device down due to noise on VIN.  
The VBIAS regulator provides internal analog and digital  
blocks with a stable supply voltage over variations in  
junction temperature and input voltage. A high quality,  
low-ESR, ceramic bypass capacitor is required on the  
VBIAS pin. X7R or X5R grade dielectrics are  
recommended because their values are more stable over  
temperature. The bypass capacitor should be placed close  
to the VBIAS pin and returned to AGND. External loading  
on VBIAS is allowed, with the caution that internal circuits  
require a minimum VBIAS of 2.70 V, and external loads on  
VBIAS with ac or digital switching noise may degrade  
performance. The VBIAS pin may be useful as a reference  
voltage for external circuits.  
Slow-Start/Enable (SS/ENA)  
The slow-start/enable pin provides two functions; first, the  
pin acts as an enable (shutdown) control by keeping the  
device turned off until the voltage exceeds the start  
threshold voltage of approximately 1.2 V. When SS/ENA  
exceeds the enable threshold, device start up begins. The  
reference voltage fed to the error amplifier is linearly  
ramped up from 0 V to 0.891 V in 3.35 ms. Similarly, the  
converter output voltage reaches regulation in  
approximately 3.35 ms. Voltage hysteresis and a 2.5-µs  
falling edge deglitch circuit reduce the likelihood of  
triggering the enable due to noise.  
Voltage Reference  
The voltage reference system produces a precise Vref  
signal by scaling the output of a temperature stable  
bandgap circuit. During manufacture, the bandgap and  
scaling circuits are trimmed to produce 0.891 V at the  
output of the error amplifier, with the amplifier connected  
as a voltage follower. The trim procedure adds to the high  
precision regulation of the TPS54311 16, since it cancels  
offset errors in the scale and error amplifier circuits.

The oscillator frequency can be set to internally fixed  
values of 350 kHz or 550 kHz using the FSEL pin as a static  
digital input. If a different frequency of operation is required  
for the application, the oscillator frequency can be  
externally adjusted from 280 kHz to 700 kHz by connecting  
a resistor to the RT pin to ground and floating the FSEL pin.  
The switching frequency is approximated by the following  
equation, where R is the resistance from RT to AGND:

The second function of the SS/ENA pin provides an  
external means of extending the slow-start time with a  
low-value capacitor connected between SS/ENA and  
AGND. Adding a capacitor to the SS/ENA pin has two  
effects on start-up. First, a delay occurs between release  
of the SS/ENA pin and start up of the output. The delay is  
proportional to the slow-start capacitor value and lasts until  
the SS/ENA pin reaches the enable threshold. The  
start-up delay is approximately:

Second, as the output becomes active, a brief ramp-up at

slow-start time set by the capacitor is approximately:

values of 4.7 µH to 10 µH are typical and available from  
several vendors. The resulting designs exhibit good noise  
and ripple characteristics, along with exceptional transient  
response. Transient recovery times are typically in the  
range of 10 to 20 µs.  
turn-on times of the MOSFET drivers. The high-side driver  
does not turn on until the gate drive voltage to the low-side  
FET is below 2 V. The low-side driver does not turn on until  
the voltage at the gate of the high-side MOSFETs is below  
2 V. The high-side and low-side drivers are designed with  
300-mA source and sink capability to quickly drive the  
power MOSFETs gates. The low-side driver is supplied  
from VIN, while the high-side drive is supplied from the  
BOOT pin. A bootstrap circuit uses an external BOOT  
capacitor and an internal 2.5-bootstrap switch  
connected between the VIN and BOOT pins. The  
integrated bootstrap switch improves drive efficiency and  
reduces external component count.  
PWM Control  
Signals from the error amplifier output, oscillator, and  
current limit circuit are processed by the PWM control  
logic. Referring to the internal block diagram, the control  
logic includes the PWM comparator, OR gate, PWM latch,  
and portions of the adaptive dead-time and control logic  
block. During steady-state operation below the current  
limit threshold, the PWM comparator output and oscillator  
pulse train alternately reset and set the PWM latch. Once  
the PWM latch is set, the low-side FET remains on for a  
minimum duration set by the oscillator pulse duration.  
During this period, the PWM ramp discharges rapidly to its  
valley voltage. When the ramp begins to charge back up,  
the low-side FET turns off and high-side FET turns on. As  
the PWM ramp voltage exceeds the error amplifier output  
voltage, the PWM comparator resets the latch, thus  
turning off the high-side FET and turning on the low-side  
FET. The low-side FET remains on until the next oscillator  
pulse discharges the PWM ramp.  
Overcurrent Protection  
The cycle by cycle current limiting is achieved by sensing  
the current flowing through the high-side MOSFET and  
differential amplifier and comparing it to the preset  
overcurrent threshold. The high-side MOSFET is turned  
off within 200 ns of reaching the current limit threshold. A  
100-ns leading edge blanking circuit prevents false  
tripping of the current limit. Current limit detection occurs  
only when current flows from VIN to PH when sourcing  
current to the output filter. Load protection during current  
sink operation is provided by thermal shutdown.  
During transient conditions, the error amplifier output  
could be below the PWM ramp valley voltage or above the  
PWM peak voltage. If the error amplifier is high, the PWM  
latch is never reset and the high-side FET remains on until  
the oscillator pulse signals the control logic to turn the  
high-side FET off and the low-side FET on. The device  
operates at its maximum duty cycle until the output voltage  
rises to the regulation set-point, setting VSENSE to  
Thermal Shutdown  
The device uses the thermal shutdown to turn off the power  
MOSFETs and disable the controller if the junction  
temperature exceeds 150°C. The device is released from  
shutdown when the junction temperature decreases to  
10°C below the thermal shutdown trip point and starts up  
under control of the slow-start circuit. Thermal shutdown  
provides protection when an overload condition is  
sustained for several milliseconds. With a persistent fault  
condition, the device cycles continuously; starting up by  
control of the soft-start circuit, heating up due to the fault,  
and then shutting down upon reaching the thermal  
shutdown point.  
approximately the same voltage as V . If the error  
ref  
amplifier output is low, the PWM latch is continually reset  
and the high-side FET does not turn on. The low-side FET  
remains on until the VSENSE voltage decreases to a  
range that allows the PWM comparator to change states.  
The TPS54311 16 is capable of sinking current  
continuously until the output reaches the regulation  
set-point.  
Power Good (PWRGD)  
If the current limit comparator trips for longer than 100 ns,  
the PWM latch resets before the PWM ramp exceeds the  
error amplifier output. The high-side FET turns off and  
low-side FET turns on to decrease the energy in the output  
inductor and consequently the output current. This  
process is repeated each cycle in which the current limit  
comparator is tripped.  
The power good circuit monitors for under voltage  
conditions on VSENSE. If the voltage on VSENSE is 10%  
below the reference voltage, the open-drain PWRGD  
output is pulled low. PWRGD is also pulled low if VIN is  
less than the UVLO threshold, or SS/ENA is low, or  
thermal shutdown is asserted. When VIN = UVLO  
threshold, SS/ENA = enable threshold, and VSENSE >  
Dead-Time Control and MOSFET Drivers  
90% of V , the open drain output of the PWRGD pin is  
ref  
Adaptive dead-time control prevents shoot-through  
current from flowing in both N-channel power MOSFETs  
during the switching transitions by actively controlling the  
high. A hysteresis voltage equal to 3% of V and a 35-µs  
falling edge deglitch circuit prevent tripping of the power  
good comparator due to high frequency noise.

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.
