DESCRIPTION
The SWIFT family of dc/dc regulators, the TPS54611,
TPS54612, TPS54613, TPS54614, TPS54615 and
TPS54616 low-input voltage high-output current
synchronous-buck PWM converters integrate all required
active components. Included on the substrate are true,
high-performance, voltage error amplifiers that provide
high performance under transient conditions; 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 power good
output useful for processor/logic reset, fault signaling, and
supply sequencing.
The TPS546116 devices are 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.
