... TK65600B The TK65600 is an inductive white LED driver circuit. The input voltage is 2. 6V. The load is represented by white LED’s - one or more parallel strings of LED’s, each string consisting of two or more LED’s connected in series. The absolute maximum voltage allowed at the output pin is 16V, dictated by wafer process limits. The forward drop voltage of the LED’ ...
