It operates in inductor current boundary conduction mode. With source driving architecture, special demagnetization sensing technology and the ultra low operating current, FT886xx doesn’t need the auxiliary winding for output current sensing and chip power supplying. FT886x also integrates a 500V power MOSFET 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 d...
