NCL30386LED1GEVB: 60W, 1.5A @ 40V Max, PFC Dimmable LED Driver


The NCL30386LED1GEVB is a power factor corrected controller targeting isolated and non−isolated “smart−dimmable” constant−current LED drivers. Designed to support flyback, buck−boost and SEPIC topologies, the controller operates in a quasi−resonant mode to provide high efficiency. Thanks to a novel control method, the device is able to tightly regulate a constant LED current and voltage from the primary side. This removes the need for secondary−side feedback circuitry, its biasing and for an optocoupler. The device also provides near−unity power factor correction.

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 digital dimming with two dedicated dimming inputs control ideal for Smart LED Lighting applications.
