MAX1719 Datasheet (Maxim) - Switched-Capacitor Voltage Inverters

MAX1719, Switched-Capacitor Voltage Inverters

The ultra-small MAX1719/MAX1720/MAX1721 monolithic, CMOS charge-pump inverters accept input voltages ranging from +1.5V to +5.5V.

The MAX1720 operates at 12kHz, and the MAX1719/MAX1721 operate at 125kHz.

High efficiency, small external components, and logiccontrolled shutdown make these devices idea
