The PW5410A is a low noise, constant 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 small bypass capacitors at VIN and VOUT) make the PW5410A ideally suited for small, battery-powered applications.
The new charge-pump architecture maintains constant switching frequency to no load and reduces
both output and input ripple. The PW5410A have 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.
