As a member of the SWIFT(TM) family of dc/dc regulators,the TPS54373 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 forprocessor/logic reset, fault signaling, and supply sequencing. For reliable power up in output precharge applications,the TPS54373 is designed to only source current during start-up. The TPS54373 is available in a thermally enhanced20-pin TS SOP (PWP) PowerPAD(TM) package, which eliminates bulky heat sinks. TI provides evaluation modules and the SWIFT(TM) designer software tool to aid in quickly achieving high-performance power supply designs to meet aggressive equipment development cycles.
