Analog/Digital DPFC Q-R Primary Side C-M Controller for LED Lighting NCL30086 www.onsemi.com 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 quasiresonant mode to provide optimal efficiency. The current control algorithm supports SOIC10 flyback, buckboost, and SEPIC topologies. Thanks to a novel control CASE 751BQ method, the device is able to tightly regulate a constant LED current from the primary side. This removes the need for secondary side MARKING DIAGRAM feedback circuitry, biasing and an optocoupler. The device is highly integrated with a minimum number of external L30086x components. A robust suite of safety protection is built in to simplify ALYW 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 L30086x = Specific Device Code current foldback circuit is also provided. The NCL30086 is housed in x = A, B, C, D the SOIC10 which has the same body size as a standard SOIC8.
