General Description

CX2905 is a highly integrated solution for SMPS applications requiring CV (constant voltage) and CC (constant current) modes.

CX2905 integrates one voltage reference, two operational amplifiers (the outputs are OR’ed together, common collectors), and a current sensing circuit.

The voltage reference, together with one operational amplifier, makes it an ideal voltage controller.
