VOLTAGE AND CURRENT CONTROL IC

■GENERAL DESCRIPTION

The NJM2346 is a low power operation battery charger IC.

It includes a voltage reference and two operational amplifiers for

voltage and current control needed for a design of secondary circuit

for battery chargers and switching regulators.

Low current consumption design contributes low standby power

required for 1A class battery chargers.
