General Description
The G5931 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 0.45m A at 3.3V supply.
The G5931 can deliver 25m A output current with a voltage drop of 250m V. The parts are over -temperature...
