As members of the SWIFT? family of DC - DC regulators, the TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316PWP low-input-voltage high-outputcurrent 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 powergood output useful for processor/logic reset, fault signaling, and supply sequencing.
The TPS54311, TPS54312, TPS54313, TPS54314, TPS54315 and TPS54316PWP devices are available in a thermally enhanced 20-pin HTSSOP (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.
