DescriptionThe 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, TPS54611,TPS54612, TPS54613, TPS54614, TPS54615 and TPS54616 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 (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.
