The TPS54010 low-input voltage, high-output current synchronous buck PWM converter in a
dc/dc regulator integrating 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 heat
sinks.
