Power Factor Corrected LED Driver Featuring Primary Side CC / CV Control NCL30388 The NCL30388 is a power factor corrected controller targeting isolated and non isolated constant current LED drivers.

Designed to support flyback, buck boost and SEPIC topologies, the controller operates in a quasi resonant mode to provide high efficiency.

Due to a novel control method, the device is able to tightly regulate a constant LED current from the primary side and provides near
