NCL30088 Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting with Thermal Foldback The NCL30088 is a power factor corrected flyback controller targeting isolated and non isolated constant current LED drivers.

The controller operates in a quasi resonant mode to provide optimal efficiency.

Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side.

This removes the need for secondary
