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.
