NCL30100 Fixed Off Time Switched Mode LED Driver Controller The NCL30100 is a compact switching regulator controller intended for space constrained constant current high brightness LED driver applications where efficiency and small size are important. The controller is based on a peak current, quasi fixed off time control architecture optimized for continuous conduction mode step down (buck) operation. This allows the output filter capacitor to be eliminated. In this con.
