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.
