Low Input Voltage 3A Synchronous Buck Converter With 1.8V Output

As members of the SWIFT family of DC/DC Regulators the TPS54311 TPS54312 TPS54313 TPS54314 TPS54315 and TPS54316 low-input-voltage high-output-current synchronous-buck PWM convertersintegrate all required active components. Included on the substrate with the listed features are a true, high performance, voltage error Amplifier that provides fast response 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 TPS54311 TPS54312 TPS54313 TPS54314 TPS54315 and TPS54316 devices devices are 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.
