NCL30082 Dimmable Quasi-Resonant 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.
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/digit...
