NCL30188
Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting with Thermal Foldback

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. The device is highly integrated with a minimum number of external components.
