UCC28711 - Constant-Current Controller
The UCC2871x family of flyback power supply controllers 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
