The loop compensation components are also removed while maintaining stability over all operating conditions. It uses a source drive architecture and patent demagnetization sensing technology with very low operating current, Patents of self power supply technology. the auxiliary winding for sensing the output and supplying the chip is therefore eliminated, resulting in low component counts and small system size. 

          With its highly accurate current sense method, the FT8350x realizes ±3% accuracy of LED current along with excellent line and load regulation.

          The multi-protection function of FT8350x can greatly enhance the system reliability and safety. The FT8350x features LED open/short circuit protection, CS resistor short circuit protection, over temperature compensation and VCC UVLO protection.
