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
SOIC−10

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.
