XA2320B Overview
The XA2320B is a low noise, constant frequency (1.2MHz) switched capacitor voltage doubler. It produce a regulated output voltage from a 1.8V to 5V input with up to 150mA of output current. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the XA2320B ideally suited for small, battery-powered applications.
