HX4004 Datasheet (Hexin Semiconductor) - Regulated Charge Pump DC/DC Converter

HX4004, Regulated Charge Pump DC/DC Converter

The HX4004 is a low noise, constant frequency (400kHz) switched capacitor voltage doubler.

It produces a regulated output voltage from a 2.8V to 5.0V input.

Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the HX4004 ideally suited for small, batte
