Dimmable Quasi-Resonant

Primary Side Current-Mode

Controller for LED Lighting

http://onsemi.com

The NCL30081 is a PWM current mode controller targeting isolated

flyback and non−isolated constant current topologies. The controller

operates in a quasi−resonant mode to provide high efficiency. Thanks

to a novel control method, the device is able to precisely 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. It supports step dimming by monitoring the AC line

and detecting when the line has been toggled on−off−on by the user to

reduce the light intensity in 5 steps down to 5% dimming.
