DESCRIPTION
As members of the SWIFT family of dc/dc regulators, the
TPS54311,
TPS54312,
TPS54313,
TPS54314,
TPS54315 and TPS54316 low-input-voltage high-output-
current synchronous-buck PWM converters integrate all
required active components. Included on the substrate
with the listed features are a true, high performance,
voltage error amplifier that provides high performance
under transient conditions; an undervoltage-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 power good output useful for
processor/logic reset, fault signaling, and supply
sequencing.
The TPS54311, TPS54312, TPS54313, TPS54314,
TPS54315 and TPS54316 devices are available in a
thermally enhanced 20-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.
