NCL30000
Power Factor Corrected
Dimmable LED Driver
The NCL30000 is a switch mode power supply controller intended
for low to medium power single stage power factor (PF) corrected
LED Drivers. The device is designed to operate in critical conduction
mode (CrM) and is suitable for flyback as well as buck topologies. http://onsemi.com
