Type: AC-DC LED Driver

Product Details: NCL30186DDR2G——Analog/Digital Dimmable Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting.

Overview

NCL30186DDR2G is an AC-DC power factor corrected flyback controller targeting isolated and non−isolated “Smart−dimmable” constant current LED drivers.

NCL30186DDR2G controller operates in a quasi−resonant mode to provide optimal efficiency. The current control algorithm supports flyback, buck−boost, and SEPIC topologies.

Thanks to a novel control method, the NCL30186DDR2G is able to tightly regulate a constant LED currentfrom the primary side. This removes the need for secondary side feedback circuitry, biasing and an optocoupler.

The NCL30186DDR2G is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design.

NCL30186DDR2G is specifically intended for very compact space efficient designs and supports analog and PWM dimming with a dedicated dimming input intended to control the average LED current. To ensure reliable operation at elevated temperatures, a user configurable current foldback circuit is also provided.
