MAX871 Datasheet (Maxim) - Switched-Capacitor Voltage Inverters

MAX871, Switched-Capacitor Voltage Inverters

The ultra-small MAX870/MAX871 monolithic, CMOS charge-pump inverters accept input voltages ranging from +1.4V to +5.5V.

The MAX870 operates at 125kHz, and the MAX871 operates at 500kHz.

Their high efficiency (90%) and low operating current (0.7mA for the MAX870) make these devices ideal for both bat
