www.DataSheet4U.com MAX1720 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 mA, and a power saving shutdown input is provided to further reduce the current to a mere 0.4 mA. The device contains a 12 kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26 W and a voltage conversion efficiency of 99%. This device requires only two external 10 mF capacitors for a complete inverter making it an ideal solution for numerous battery powered and board level applications.
