TPS54610MPWPREP

As a member of the SWIFT™ family of dc/dc regulators, the TPS54610 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 inrush currents, and a power good output useful for processor/logic reset, fault signaling, and supply sequencing. The TPS54610 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which eliminates bulky heatsinks.
