Other Parts Discussed in Thread: UCC28221

Hi all,
Please let us know about UCC28221.
We know, this device is current-mode controller.
Can we use the resister instead of current-trans?

Hi Yoshitaka-san

It should be possible to use resistive current sense. I suggest to add a series RC filter circuit between the CS resistor and the CS pin to filter out the leading edge spike.

Regards

Peter
