G5934 Global Mixed-mode Technology Inc. High Voltage 1.5x Charge Pump with Load Switch Controller Features General Description The G5934 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 150µA at 8V supply and 190µA at 24V supply. Input Range: 8V to 24V Output Range: 12V to 36V 150µA Quiescent Current at 8V Supply Voltage and 190µA Quiescent Current at 24V Supply Voltage ±3% Regulated Output Power Good Function Power Good of Open Drain (Monitor AC VIN Only) Embedded a 12-V LDO 4 Control Signal Inputs 4 12V-Drivers for external NMOS switches 4 Discharging Networks for 22Ω Over-Temperature Protection Output Short Circuit Protection TQFN3X3-20 Package The G5934 has a NMOS open-drain output pin for power good indication. When VOUT > 1.5 x VIN x 90%, the NMOS will be turned off immediately and PG pin will be pulled high by external resistor. The G5934 contains an embedded 12-V LDO to provide the supply voltage to the drivers controlled by ON signals. The discharging networks are connected to the 22Ω resistor to shut down the low-voltage system while control input signals ON are not ready. The G5934 contains an over-temperature circuit to protect the device under continuous output short circuit conditions. Applications Notebook Computers The G5934 is available in TQFN3X3-20 package (thermal pad included). Ordering Information ORDER NUMBER MARKING TEMP.
