Overview

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.
