Pin N5 Pin Name Function 1 CS Current sense input 2 GND Ground 3 CT Timing capacitor 4 IVC Input voltage compensation 5 VCC Input supply 6 DRV Driver output Pin Description A resistor divider consisting of R3 and R4 is used to set the peak current sensed through the MOSFET switch Power
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.
