Primary Side Current-Mode
Controller for LED Lighting
with Thermal Fold-back
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.

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.
