General Description

The CP103 is a monolithic IC specifically designed

to regulate the output current and voltage levels of

switching battery chargers and power supplies.

The device contains two Op Amps and a 2.5V preci-

sion shunt voltage reference. Op Amp 1 is designed for

voltage control with its non-inverting input internally

connects to the output of the shunt regulator. Op Amp

2 is for current control with both inputs uncommitted.

The IC offers the power converter designer a control

solution that features increased precision with a corre-

sponding reduction in system complexity and cost.

The CP103 is available in standard packages of DIP-

8 and SOP-8.
