MAX829 Datasheet (Maxim) - Switched-Capacitor Voltage Inverters

MAX829, Switched-Capacitor Voltage Inverters

The ultra-small MAX828/MAX829 monolithic, CMOS charge-pump inverters accept input voltages ranging from +1.5V to +5.5V.

The MAX828 operates at 12kHz, and the MAX829 operates at 35kHz.

Their high efficiency (greater than 90% over most of the load-current range) and low operating current (60µA for the
