Power Factor Corrected Dimmable LED Driver 8-Pin SOIC N T/R

The NCL30000 is a switch mode power supply controller intended for low to medium power single stage power factor (PF) corrected isolated flyback LED Drivers. It employs a Critical Conduction Mode (CrM) control technique to ensure near unity power factor across a wide range of input voltages and output power.
