HX4004A - Regulated Charge Pump DC/DC Converter

Datasheet Summary

Description

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.

Features

  • Fixed 4.94V±3% Output.
  • VIN Range: 2.7V to 4.5V.
  • Output Current: Up to 110mA (VIN≥3V) Up to 230mA (VIN≥3.6V).
  • Low Noise Constant Frequency (360kHz) Operation.
  • Shutdown Current.
