Low Input Voltage 6A Synchronous Buck Converter With Disabled Sinking During Start Up

As a member of the SWIFT? family of DC/DC Regulators the TPS54673 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 enables maximum performance and flexibility in choosing the output Filter L and C components; an under-voltage-lockout circuit to prevent start-up until the input voltage reaches 3 V; an internally or 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.
For reliable power up in output precharge applications, the TPS54673 is designed to only source current during startup.
The TPS54673 is available in a thermally enhanced 28-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.
