产品简介 :

The FT8783NX controller device is optimized for high-performance, low power switching mode power supply applications. The FT8783NX facilitates CC/CV charger design by eliminating an opto-coupler and TL431. Its highly integrated functions such as Under Voltage Lockout (UVLO), Leading Edge Blanking (LEB) and built-in cable compensation offer the users a high efficiency and low cost solution for AC/DC power applications.  

Power supplies built with FT8783NX can achieve both highest average efficiency， fast dynamic load response and super low standby power. FT8783NX satisfy DoE Level 6 /CoC V5 Tier2 requirements with production margin.

Furthermore, FT8783NX features fruitful protections like Open Circuit Protection and Over Temperature Protection to eliminate the external protection circuits and provide reliable operations.
