NCL30081 Dimmable Quasi-Resonant Primary Side Current-Mode Controller for LED Lighting 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 op.
