G5933 Global Mixed-mode Technology Inc. High Voltage 1.5x Charge Pump General Description Features The G5933 is a high-voltage switched-capacitor charge pump that provides the regulated output voltage of 1.5x input voltage. Input voltages ranging from 8V to 24V can be converted into a 12V to 36V output supply. The device is ideal for battery-powered conversion applications in notebook computers with a typical operating current of 56µA at 8V supply and 96µA at 24V supply. The G5933 can deliver 10mA output current with a voltage drop of 900mV at 24V supply. Input Range: 8V to 24V Output Range: 12V to 36V 56µA Quiescent Current at 8V Supply Voltage and 96µA Quiescent Current at 24V Supply Voltage ±3% Regulated Output 10mA Output Current with a Voltage Drop of 900mV Power Good Function Over-Temperature Protection MSOP-8 Package The G5933 has a NMOS open-drain output pin for power good indication. When VOUT > 1.5 *VIN* 90%, the NMOS will be turned off immediately and PG pin will be pulled high by external resistor. Applications The G5933 contains an over-temperature circuit to protect the device under continuous output short circuit conditions. The device is available in a 8-pin MSOP package.
