UCC28722 Datasheet (Texas Instruments) - Constant-Current Controller

UCC28722, Constant-Current Controller

The UCC28722 flyback power supply controller provides isolated-output constant-voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler.

The device processes information from the primary power switch and an auxiliary flyback winding for precise control of output
