![]() ![]() ![]() Pin-to-pin compatible to the NC元0088, the NC元0188 provides the same benefits with in addition, an increased resolution of the digital current-control algorithm for a 75% reduction in the LED current quantization ripple.Ĩ 元0188x ALYW 元0188x = Specific Device Code A = Assembly Location L = Wafer Lot Y = Year W = Work Week G = Pb-Free Package To ensure reliable operations at elevated temperatures, a user configurable current foldback circuit is also provided. A robust suite of safety protections is built in to simplify the design. The device is highly integrated with a minimum number of external components. Housed in the SOIC8, the NC元0188 is specifically intended for very compact space-efficient designs. ![]() Designed to support flyback, buck-boost, and SEPIC topologies, its proprietary current-control algorithm provides near-unity power factor and tightly regulates a constant LED current from the primary side, thus eliminating the need for a secondary-side feedback circuitry or an optocoupler. The is a controller targeting isolated and non-isolated "smart-dimmable" constant-current LED drivers.
