Thermal Foldback
The NCL30185 is a controller targeting isolated and non−isolated “smart−dimmable” constant−current LED drivers.
Designed to support flyback, buck−boost, and SEPIC topologies, its proprietary current−control algorithm provides near−unity power factor and
8
1 SOIC−8 NB CASE 751
tightly regulates a constant LED current from the primary side, thus eliminating the need for a secondary−side feedback circuitry or an optocoupler.
Housed in the SOIC8, the NCL30185 is specifically intended for very compact space−efficient designs.
