Thanks to the members of SWIFT's ™ DC/DC regulator family, TPS54972 low input voltage high output current synchronous step-down PWM converters integrate all the required active ingredients. Included in the listed features with the substrate is a true, high-performance, voltage-error amplifier capable of selecting output filtered inductor and capacitor components in transient conditions and maximum flexibility; a secondary voltage latching circuit to prevent start-up until the input voltage reaches 3.0 volts; Slow start circuit is set internally to limit inrush current; and status output indicate effective operating conditions.

The TPS54972 is to package the PowerPAD™ with a thermally enhanced 28-pin TSSOP (Works), eliminating bulky heat sinks.
