Hello,

I wish to add slope compensation to a self oscillating boost converter, it is 12V input and Vout = 90V (its 36 amber leds in series at I = 30mA).

The circuit inductor squeals like mad, and i wish to add slope compensation, -there is no oscillator, so i suppose i have to couple the drain volage back to the source current sense as a kind of slope compensation?

Dear grizedale
Hi
I think your problem will solve if you use a simple snubber network .
