MAX1720 Switched Capacitor Voltage Inverter

The MAX1720 charge pump converter inverts the voltage applied to the Vin pin. Conversion consists of a two *phase operation (Figure 15). During the first phase, switches S2 and S4 are open and S1 and S3 are closed. During this time, C1 charges to the voltage on Vin and load current is supplie.

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, yieldi.
