UCC28700 Datasheet - Texas Instruments

UCC28700 Constant-Current Controller

The UCC28700 family of flyback power supply controllers provides 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 volta.
