MAX1721 - 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
