MAX1720: 50 mA, 12 kHz Switched Capacitor Voltage Inverter with Shutdown

The MAX1720 is a CMOS charge pump voltage inverter that is designed for operation over an input voltage range of 1.15 V to 5.5 V with an output current capability in excess of 50 mA. The operating current consumption is only 67 ?A, and a power saving shutdown input is provided to further reduce the current to a mere 0.4 ?A. The device contains a 12 kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26 ? and a voltage conversion efficiency of 99%. This device requires only two external 10?F capacitors for a complete inverter making it an ideal solution fornumerous battery powered and board level applications. The MAX1720 is available in the space saving TSOP-6 thin(SOT-23-6) package.
