Low Input Voltage 3A Synchronous Buck Converter With Adjustable Output Voltage

As members of the SWIFT? family of DC/DC Regulators the TPS54310 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 TPS54310 device 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.
