SCM1702A Description
SCM1702A is a flyback primary side power supply controller. It provides isolated Constant Voltage (CV) and Constant Current (CC) output without using an opto-coupler. The devices processes information from the primary power switch and an auxiliary flyback winding for precise control of the output voltage and current.
