    NCL30086 Analog/Digital Dimmable Power Factor Corrected Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting
    The NCL30086 is a power factor corrected flyback controller targeting isolated and non-isolated "Smart-dimmable" constant current LED drivers. The 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 device is able to tightly regulate a constant LED current from the primary side. This removes the need for secondary side feedback circuitry, biasing and an optocoupler. The device is highly integrated with a minimum number of external components. A robust suite of safety protection is built in to simplify the design. This device 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. The NCL30086 is housed in the SOIC10 which has the same body size as a standard SOIC8.
