DESCRIPTION

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.

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.
