Auxiliary power supplies Functional 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. With its internal 650V startup switch, the SCM1702A can be started in a wide range of input voltage, and being supplied by the transformer auxiliary winding, the chip’s power consumption remains relatively low. The SCM1702A controller provides high performance, output precision, advanced dynamic response and low output temperature coefficient due to numerous built-in auxiliary and compensation functions. The built-in functions include protection for over temperature, output overvoltage and over current, feedback (FB pin) and current share (CS pin) faults, so the safety requirements can be easily met.
