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 4.5V input. Low external parts count (one flying capacitor and two small bypass capacitors at VIN and VOUT) make the HX4004 ideally suited for small, batt Ø   Fixed 5V ± 4% Output\nØ   VIN Range: 2.8V to 4.5V\nØ   Output Current: Up to 100mA（VIN≥2.8V）\n                                  Up to 250mA（VIN≥3.6V）\nØ   Constant Frequency Operation at All Loads \nØ   Low Noise Constant Frequency (400kHz) Operation\nØ   Automatic Soft-Start Reduces Inrush ;
