MAX619 Datasheet (Maxim) - Regulated 5V Charge-Pump DC-DC Converter

MAX619, Regulated 5V Charge-Pump DC-DC Converter

The MAX619 step-up charge-pump DC-DC converter delivers a regulated 5V ±4% output at 50mA over temperature.

The input voltage range is 2V to 3.6V (two battery cells).

The complete MAX619 circuit fits into less than 0.1in2 of board space because it requires only four external capacitors: two 0.22µ F
