FT8852A

产品简介 :

FT8852x is optimized for low cost non-isolated Buck switching mode LED driver applications. It operates in inductor current boundary conduction mode. With source driving architecture, special demagnetization sensing technology and the ultra low operating current, FT8852x doesn’t need the auxiliary winding for output current sensing and chip power supplying. FT8852x also integrates a 700V power NPN that further improves the system reliability and lowers the system cost and complexity.

Its highly integrated functions such as Leading Edge Blanking (LEB) and built-in line compensation offer users a high efficiency and low cost solution for constant current LED driver applications.

The multi-protection function of FT8852x greatly enhances the system reliability and safety. FT8852x offers fruitful protections like LED open and short circuit protection, over temperature compensation, CS resistor short circuit protection.

The industry's advanced OVP voltage accuracy ensures good LED open circuit protection.
