DescriptionAs members of the SWIFT family of dc/dc regulators, the TPS54310QPWPRQ1 low-input-voltage high-output-current synchronous-buck PWM converter integrates 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 power good output useful for processor/logic reset, fault signaling, and supply sequencing.
The TPS54310QPWPRQ1 device is available in a thermally enhanced 20-pin TSSOP (PWP) PowerPAD? package, which eliminates bulky heatsinks. Texas Instruments 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.
