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 current control. This device is a monolithic IC that includes one independent 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 solution for low cost charging applications.
