MAX828, MAX829 Switched Capacitor Voltage Converter The MAX828 and MAX829 are CMOS charge pump voltage inverters that are 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 68 mA for the MAX828 and 118 mA for the MAX829. The devices contain an internal oscillator that operates at 12 kHz for the MAX828 and 35 kHz for the MAX829. The oscillator drives four low resistance MOSFET switches, yielding a low output resistance of 26 W and a voltage conversion efficiency of 99.9%. These devices require only two external capacitors, 10 mF for the MAX828 and 3.
