DESCRIPTION
As a member of the SWIFT family of dc/dc regulators,
the TPS54810 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 3.8 V; an internally or
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 TPS54810 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.
