I have to add design circuit for 0 to10 v analog interface for PWM dimming in my existing design.anyone please share the idea and design. Schemtic.JPG

i dont understand how to do this.

already the circuit have dimming logic but i think that is for TRIAC dimming.
 

No, Actually IC has provision for inbuilt PWM so i have to add the design ckt for dimming, whaterver flyback converter output is again feed to the FB i.e feedback pin of TPS92210 ,so IC control the Dimming feature.
but i dnt understand how we can add the design logic for dimming.could you please help me out.
