NCL30082

Dimmable Quasi-Resonant

Primary Side Current-Mode

Controller for LED Lighting

with Thermal Fold-back

http://onsemi.com

The NCL30082 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 supports analog/digital dimming as well as

thermal current fold−back. While the NCL30082 has integrated fixed

overvoltage protection, the designer has the flexibility to program a

lower OVP level.
