Description

The ST619LB is a step-up charge pump DC-DC converter which delivers a regulated 5V ±4% output at 30mA and over temperature. The input voltage range is 2V to 3.6V (two battery cells). It requires only four external capacitor: two 0.22F flying capacitors, and 10F capacitors at the input and output.

Low operating supply current (typ 200mA) make the device ideal for small, portable and battery powered applications. When shut down the load is disconnected from the input and the supply current is typically 0.02A. The ST619LB is available in SO-8 and DIP-8 packages.
