MAX866 Datasheet (Maxim) - 3.3V/5V or Adjustable-Output / Single-Cell DC-DC Converters

MAX866, 3.3V/5V or Adjustable-Output / Single-Cell DC-DC Converters

The MAX866 and MAX867 are ultra-small, high-efficiency, CMOS, step-up, DC-DC switching regulators for 1-cell battery-powered systems.

The MAX866 accepts a positive input voltage between 0.8V and VOUT and converts it to a higher, pin-selectable output voltage of 3.3V or 5V.

The MAX867 adjustable vers
