ST619LB

DC-DC converter regulated 5 V charge pump

Features

■ Regulated 5 V ±4 % charge pump

■ Output current guaranteed over temperature:

20 mA (VI ≥ 2 V), 30 mA (VI ≥ 3 V)

■ No inductors; very low EMI noise

■ Uses small, inexpensive capacitors

■ Logic controlled 1 µA max shut-down supply

current

■ Shut down disconnects load from input

■ Available in SO-8 and DIP-8 packages

Description

The ST619LB is a step-up charge pump DC-DC

converter which delivers a regulated 5 V ±4 %

output at 30 mA and over temperature. The input

voltage range is 2 V to 3.6 V (two battery cells).

It requires only four external capacitor: two

0.22 µF flying capacitors, and 10 µF capacitors at

the input and output.

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

available in SO-8 package.
