SIMPLIFIED SCHEMATIC
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 TPS54611–6 devices are available in a thermally
enhanced
28-pin
TSSOP
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.
