UCC28711DR Datasheet PDF - TI

●DESCRIPTION

●The UCC28710 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 of output voltage and current.
