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 μA, and a power saving shutdown input is provided to further reduce the current to a mere 0.4 μA. The device contains a 12 kHz oscillator that drives four low resistance MOSFET switches, yielding a low output resistance of 26 Ω and a voltage conversion efficiency of 99. This device requires only two external 10μF capacitors for a complete inverter making it an ideal solution for numerous battery powered and board level applications. The MAX1720 is available in the space saving TSOP−6 package.
