Said first principle. The first to present constant-current LED dedicated IC represented, mainly, such as 9910 series, AMC7150, all now playing the brand of LED constant current driver IC are basically this, and told him to constant current IC type it. But I think to do this so-called constant-current constant current IC, the effect is not how good. The control principle is relatively simple, is the primary power supply circuit, setting a current threshold, when the primary MOS turns on
