MAX828, MAX829
Switched Capacitor
Voltage Converter
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.
