MAX619
Description
The MAX619 step-up charge-pump DC-DC converter delivers a regulated 5V ±4% output at 50m A over temperature. The input voltage range is 2V to 3.6V (two battery cells). The plete MAX619 circuit fits into less than 0.1in2 of board space because it requires only four external capacitors: two 0.22µ F flying capacitors, and 10µ F capacitors at the input and output. Low operating supply current (150 µA max) and low shutdown supply current (1µA max) make this device ideal for small, portable, and battery-powered applications. When shut down, the load is disconnected from the input. The MAX619 is available in 8-pin DIP and SO packages.
