Dimmable Power Factor
Corrected LED Driver
Featuring Primary Side CC /
CV Control
The NCL30386 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. www.onsemi.com MARKING
