Description

The device is is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) mode.

It integrates one voltage reference, two operational amplifiers (with ORed outputs - common collectors), and a current sensing circuit.

The voltage reference combined with one operational amplifier makes it an ideal voltage controller; the current sensing circuit and the other operational amplifier make up the current control loop.
