% Y4 K4 B0 Q vThe PS3120A is a low noise switched capacitor voltage doubler. It produces a regulated output voltage from a 2.7V to 4.5V input. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the PS3120A ideally suited for small, battery-powered applications.
