MAX829SNTR Datasheet PDF - ON Semiconductor

Switched Capacitor Voltage Converters

●The MAX828/829 are CMOS “charge–pump” voltage converters in ultra–small SOT–23 5 lead packages. They invert and/or double an input voltage which can range from +1.5V to +5.5V. Conversion efficiency is typically >95%. Switching frequency is 12kHz for the MAX828 and 35kHz for the MAX829.
