FUNCTION DESCRIPTIONS
SA482X67K65 is used for off-line SMPS with high voltage MOSFET and current mode PWM controller. The
PWM controller integrates the fixed frequency oscillator, the undervoltage lockout, the overvoltage protection, the
overcurrent protection, the temperature protection, and the leading edge blanking. SA482X67K65 need few
external components, increasing the efficiency and system reliability, suited for a flyback converter or a forward
converter.
