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 0.22
μ
F
flying capacitors, and 10
μ
F capacitors at the input
and output.
Low operating supply current (typ 200
μ
A) 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 0.02
μ
A. The ST619LB is
available in SO-8 and DIP-8 packages.
