Datasheet Summary
Fixed Off Time Switched
Mode LED Driver Controller
The NCL30100 is a pact 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 configuration, a reverse buck topology is used to control a cost effective N- type MOSFET. Moreover, this controller employs negative current sensing thus minimizing power dissipation in the current sense resistor. The off...
