TPS54372-Q1

SGLS267E − OCTOBER 2004 − REVISED JUNE 2008

3-A OUTPUT TRACKING/TERMINATION SYNCHRONOUS PWM

SWITCHER WITH INTEGRATED FETs (SWIFT)

FEATURES

DESCRIPTION

Qualified for Automotive Applications

As a member of the SWIFT family of dc/dc regulators,

the TPS54372 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 enables maximum

performance under transient conditions and flexibility in

choosing the output filter L and C components; an

under-voltage-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 status output to indicate valid operating

conditions.

Tracks Externally Applied Reference Voltage

60-mΩ MOSFET Switches for High Efficiency

at 3-A Continuous Output Source or Sink

Current

6% to 90% V Output Tracking Range

Wide PWM Frequency:

Fixed 350 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

APPLICATIONS

The TPS54372 is available in a thermally enhanced

20-pin TSSOP (PWP) PowerPAD package, which

eliminates bulky heatsinks. Texas Instruments 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.
