The PW5410A is a low noise, c***tant frequency (1.2MHz) switched capacitor voltage doubler. It produces a regulated output voltage from 2.7V to 5V input with up to 250mA of output current. Low external parts count (one flying capacitor and two ***all bypass capacitors at VIN and VOUT) make the PW5410A ideally suited for ***all, battery-powered applicati***.
The new charge-pump architecture maintains c***tant switching frequency to no load and reduces both output and input ripple. The PW5410A h***e thermal shutdown capability and can survive a continuous short circuit from VOUT to GND. Built-in soft-start circuitry prevents excessive inrush current during start-up.
