Product Summary
The TPS54310PWPR is a 3-v to 6-v input, 3-a output synchronous-buck pwm switcher. As members of the SWIFT family of dc/dc regulators, the TPS54310PWPR 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 TPS54310PWPR is available in a thermally enhanced 20－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.
