The FT8492XX is a high performance PWM controller for offline flyback power converter Application, with constant voltage. The FT8492XX series are enhanced high efficient multi-mode PWM flyback controller. FT8492XX operates at Continuous Conduction Mode (FT8492Gxx/FT8492Hxx) or Boundary Conduction Mode(FT8492Bxx) and achieve highest average efficiency, fast dynamic load response and ultra-low standby power. FT8492XX satisfy DoE Level VI requirements with production margin.
FT8492XX also integrates a 650V power MOS that further improves the system reliability and lowers the system cost and complexity.
The FT8492XX is available in SOP8/DIP8 package, and it is a current mode PWM controller. Muti- protection The FT8492XX features fruitful protections like Over Voltage Protection (OVP) , Over Temperature Protection (OTP), and a programmable bulk capacitor Brown-in/ Brown-out protection. Etc.
