Presentation

The controller operates in a quasiâˆ’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 foldâˆ’back. While the NCL30082 has integrated fixed overvoltage protection, the designer has the flexibility to program a lower OVP level.
