0 to 10 v analog interface for PWM dimming

I have to add design circuit for 0 to10 v analog interface for PWM dimming in my existing design. please share the idea and design.
i dont understand how to do this.

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

Can you explain what your circuit do? what range it works for.. how it work etc. and what does it controls.

Thank you very much for the reply sir.sry for the posting at wrong place.

Actually the ckt is for constant current led driver, which has output vtg 38v and 430 MA, and when no load condition output vtg is upto 60v.IC is TPS92210 from Texas instrument.

IC has feature for inbuilt PWM, but i want to add 0 to 10 v analog interface.

The inbuilt PWM function of TPS92210 is for a different purpose. Generating PWM is not going to be a problem but where are you going to feed that 10V PWM?

actually just need to dimmed the load by led driver, so that dimming should managed by PWM,so we can save the energy, then in future i will add the interface external device to give the command for On and OFF & Dimming like DALI

then put a transistor that can take load of that and control that transistor from a controller.

but how can i put transistor before the MOSFET or can i put the transistor after the Flyback converter output .

please guide us

I am not too good at power electronics, but you can put a good power transistor on LED+ line, I think?

here is the attached ckt whether it is work?
i will check with hardware testing.
