说明

As a member of the SWIFT™ family of dc/dc regulators, the TPS54010 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 under transient conditions and flexibility in choosing the output filter L and C components; an undervoltage-lockout circuit to prevent start-up until the VIN input voltage reaches 3 V; an internally and externally set slowstart circuit to limit in-rush currents; and a power-good output useful for processor/logic reset, fault signaling, and supply sequencing.

The TPS54010 is available in a thermally enhanced 28-pin TSSOP (PWP) PowerPAD™ package, which eliminates bulky heatsinks.
