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 powergood
output useful for processor/logic reset, fault signaling, and supply sequencing.
The TPS5461x 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.
