UCC28720 Datasheet (Texas Instruments) - Constant-Current Controller

UCC28720, Constant-Current Controller

The UCC28720 flyback power supply controller provides isolated-output Constant-Voltage (CV) and Constant-Current (CC) output regulation without the use of an optical coupler.

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