描述 Description

The FT8393NDx is a Flyback controller targeting at high-performance Constant Current/Constant Voltage applications. The FT8393NDx facilitates CC/CV charger design by eliminating an opto-coupler and TL431. FT8393NDx operates in quasi-resonant mode and adaptive PFM control for highest average efficiency for AC/DC power applications. ?
Power supplies built with FT8393NDx can achieve both highest average efficiency, fast dynamic load response and super low standby power. FT8393NDx satisfy DoE VI and CoC Tier2 requirements with production margin for 5V/2A and 5V/2.4A applications, respectively.?
Furthermore, FT8393NDx features fruitful protections like Open Circuit Protection and Over Temperature Protection to eliminate the external protection circuits and provide reliable operations.?
When FT8393NDx is used with FT8370x, good under-shoot performance and higher conversion efficiency can be achieved
