DESCRIPTION

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

TPS54672 active bus termination synchronous 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 and flexibility in choosing the

output filter L and C components; an under-voltagelockout

circuit to prevent start-up until the input voltage

reaches 3 V; a slow-start control to limit in-rush currents;

and a status output to indicate valid operating conditions.

The TPS54672 is available in a thermally enhanced 28-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.
