ON Semiconductor NCL30001

High-Efficiency Single Stage Power Factor Correction and Step-Down Offline LED Driver


Topology Flyback Converter
Input voltage 85-265 V
Switching frequency 90-110 kHz
Output 1 100 V / 0.45 A
Output 2 48 V / 2.5 A
IC revision 1


The NCL30001 is a switch mode power supply controller intended for medium to high power single stage power factor (PF) corrected isolated flyback LED Drivers. It employs a Continuous Conduction Mode (CCM) control technique to ensure near unity power factor across a wide range of input voltages and output power.
