As a member of the SWIFT? family of dc/dc regulators, the TPS54073 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 undervoltage-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 TPS54073 is designed to only source current during start-up.
The TPS54073 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
