IP103H
Voltage and Current Controller
* The Main Differences of IP103 and IP103H are
Vicm(Input
Common Mode Voltage Range) and
Vop(Operating
Voltage)
DESCRIPTION
The IP103H is designed to be used in battery
chargers with a constant voltage and a constant cur-
rent control.
This device is a monolithic IC that includes one in-
dependent op-amp and other op-amp for which the
non inverting input is wired to a 2.5V fixed Voltage
reference.
Integrating the reference and op-amps creates a so-
lution for low cost charging applications.
