产品简介 :

The FT8393Mxx is a Flyback controller targeting at high-performance Constant Current/Constant Voltage applications. The FT8393Mxx facilitates CC/CV charger design by eliminating an opto-coupler and TL431. FT8393Mxx operates in quasi-resonant mode and adaptive PFM control for highest average efficiency for AC/DC power applications.  

Power supplies built with FT8393Mxx can achieve both highest average efficiency, fast dynamic load response and super low standby power. FT8393Mxx satisfy DoE VI and  CoC Tier2 requirements with production margin. 

Furthermore, FT8393Mxx features fruitful protections like Open Circuit Protection and Over Temperature Protection to eliminate the external protection circuits and provide reliable operations. 

When FT8393Mxx is used with FT8370x, good under-shoot performance and higher conversion efficiency can be achieved
