Description

 

 The FT8492X is a high performance PWM controller for offline flyback power converter application, with constant voltage. The FT8492X series are enhanced high efficient multi-mode PWM flyback controller. FT8492X operates at Continuous Conduction Mode (CCM) and achieve highest average efficiency, fast dynamic load response and ultra-low standby power. FT8492x satisfy DoE Level VI requirements with production margin.

 

 

 

The FT8492X is available in SOT-23-6 package, and it is a current mode PWM controller. Muti- protection and programmable functions are built-in, including a programmable propagation delay time compensation, Furthermore, The FT8492x features fruitful protections like Over Voltage Protection  (OVP) , a programmable external Over Temperature Protection (OTP), and a programmable bulk capacitor Brown-in/ Brown-out protection. Etc.

 

 

 

Especially, when BCM version FT8492B is used with our Synchronic Rectifier FT8370x series, higher conversion efficiency can be achieved.
