Dimmable Quasi-Resonant
Primary Side Current-Mode
Controller for LED Lighting
with Thermal Fold-back
The NCL30083 is a PWM current mode controller targeting isolated

flyback and nonisolated constant current topologies. The controller
operates in a quasiresonant 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

efficient designs. It supports step dimming by monitoring the AC line
