UCC28070: Use inductor current as feedback instead of mosfet current

Part Number: UCC28070

Hi there,

I was wondering if it is feasible to use the inductor current instead of the transistor current as a current feedback for the ucc28070?

Thanks,

George

    HI, George

    UCC28070 have to sense the transistor current because of Advanced Current Synthesizer Current Sensing.

    UCC28070 sense the transistor current and transfer to average current of inductor internally, so it is not working if you sense inductor current instead.
