Overview

NCL30188 Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting with Thermal Foldback www.onsemi.com The NCL30188 is a controller targeting isolated and non−isolated “smart−dimmable” constant−current LED drivers.

Designed to 8 support flyback, buck−boost, and SEPIC topologies, its proprietary current−control algorithm provides near−unity power factor and 1 SOIC−8 NB tightly regulates a constant LED current from the primary side, thus CASE 751 eliminating the need for a secondary−side feedback circuitry or an optocoupler.

Housed in the SOIC8, the NCL30188 is specifically intended for very compact space−efficient designs.
