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 0.22µF

flying capacitors, and 10µF capacitors at the input

and output.

Low operating supply current (typ 200µA) 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 0.02µA. The ST619LB is

available in SO-8 and DIP-8 packages.
