TPS54310

SLVS412A – DECEMBER 2001 – REVISED JUNE 2002

3-V TO 6-V INPUT, 3-A OUTPUT SYNCHRONOUS-BUCK PWM

SWITCHER WITH INTEGRATED FETs (SWIFT )

FEATURES

DESCRIPTION

60-mΩ MOSFET Switches for High Efficiency

at 3-A Continuous Output Source or Sink

Current

0.9-V to 3.3-V Adjustable Output Voltage With

1% Accuracy

Externally Compensated for Design Flexibility

Fast Transient Response

Wide PWM Frequency: Fixed 350 kHz, 550

kHz, or Adjustable 280 kHz to 700 kHz

Load Protected by Peak Current Limit and

Thermal Shutdown

Integrated Solution Reduces Board Area and

Total Cost

As members of the SWIFT family of dc/dc regulators,

the TPS54310 low-input-voltage high-output-current

synchronous-buck PWM converter integrates 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 voltagereaches

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.

The TPS54310 device is available in a thermally

enhanced 20-pin TSSOP (PWP) PowerPAD

package, which eliminates bulky heatsinks. TI provides

evaluation modules and the SWIFT designer software

tool to aid in quickly achieving high-performance power

supply designs to meet aggressive equipment

development cycles.

APPLICATIONS

Low-Voltage, High-Density Systems With

Power Distributed at 5 V or 3.3 V
