As a member of SWIFT's ™ DC/DC regulator family, the TPS54972 low input voltage high output current synchronous buck PWM converter integrates all the necessary active ingredients. Included in the listed features with substrate is a true, high-performance, voltage-error amplifier capable of selecting output filtering inductor and capacitor components in transient conditions and with maximum flexibility; a secondary voltage blocking circuit to prevent start-up until the input voltage reaches 3.0 volts; Internal slow start circuit to limit inrush current; and status outputs indicate valid operating conditions.

The TPS54972 is available in a thermally enhanced 28-pin TSSOP (Public Service) PowerPAD™ package, which eliminates bulky heat sinks.
