DESCRIPTION
The ST619LB is a step-up charge pump DC-DC
converter which delivers a regulated 5V
鹵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碌F
flying capacitors, and 10碌F capacitors at the input
and output.
Low operating supply current (typ 200碌A(chǔ)) 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碌A(chǔ). The ST619LB is
available in SO-8 and DIP-8 packages.
