MAX828/D

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 3.3

mF for the MAX829, for a complete inverter

making it an ideal solution for numerous battery powered and board

level applications. The MAX828 and MAX829 are available in the

TSOP−5 package.
