Hello, I learned that XDPL8221 can achieve 120- 277V input, 0- 10V dimming, and CC or CV output. These functions are what I need. I also want it to support TRIAC dimmer, can it support TRIAC dimming? Or is there any other recommended ...Read more

Hello,

I learned that XDPL8221 can achieve 120- 277V input, 0- 10V dimming, and CC or CV output. These functions are what I need.

I also want it to support TRIAC dimmer, can it support TRIAC dimming?

Or is there any other recommended IC that can achieve such a function?

Thank You

    Hi @sachinsharma, XDPL8221 has a PWM dimming interface which is implemented with the aid of CDM10V. The duty cycle sensed at the PWM pin will set the output current accordingly. Please have a look at the LED/SMPS Flyback Control IC IRS2982S which may fulfill your requirement. This driver is TRIAC diRead more

    Hi sachinsharma,

    XDPL8221 has a PWM dimming interface which is implemented with the aid of CDM10V. The duty cycle sensed at the PWM pin will set the output current accordingly.

    Please have a look at the LED/SMPS Flyback Control IC IRS2982S which may fulfill your requirement. This driver is TRIAC dimmable. Refer to the attached application note for more details.
