G5930 Global Mixed-mode Technology Inc. Switched Capacitor Voltage Inverter with Shutdown Features General Description Inverts Input Supply Voltage 60mA Output Current with a Voltage Drop of 580mV 0.45mA Quiescent Current at 3.3V Supply Voltage 99% Voltage Conversion Efficiency 1.8V to 5V operating range Require Only Two Capacitors Over-Temperature Protection Logic Controlled Shutdown 6-Pin SOT-23 Package and TDFN2X2 6-pin Package The G5930 is an unregulated charge-pump voltage inverter which may be used to generate a negative supply from positive input. Input voltages ranging from +1.8V to +5V can be inverted into a -1.8V to -5V output supply. The devices is ideal for both battery- powered and board level voltage conversion applications with a typical operating current of 0.45mA at 3.3V supply. The G5930 can deliver 60mA output current with a voltage drop of 580mV. The parts are over -temperature protected. Applications Applications include cell phones, PDAs, and other portable equipment. The devices is available in a space-saving 6-pin SOT-23 and TDFN2X2 6-pin Package.
