HX4004A Datasheet (Hexin Semiconductor) - Regulated Charge Pump DC/DC Converter

HX4004A, Regulated Charge Pump DC/DC Converter

The HX4004A 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 HX4004A ideally suited for small, battery-powered applications.
