NCL30486B Dimmable Power Factor Corrected LED Driver

NCL30486B Pin N5 Pin Name Function Pin Description 1 ADIM Analog dimming This pin is used for analog control of the output current. Applying a voltage varying between VDIM(EN) and VDIM100 will dim the output current from 0% to 100%. 2 COMP OTA output for CV loop This pin receives a compensa.

Dimmable Power Factor Corrected LED Driver Product Preview NCL30486B The NCL30486B is a power factor corrected flyback controller targeting isolated constant current LED drivers. The controller operates in a quasi resonant mode to provide high efficiency. Thanks to a novel control method, the device is able to tightly regulate a constant LED current from the primary side. This removes the need for secondary side feedback circuitry, its biasing and for an optocoupler. The device is highly.
