Tool/software: Code Composer Studio

We downloaded and use the PSFB program of this URL(www.ti.com/tool/ucd3138fw-psfb ).

We have a question related to this program.

We would like to change minmum duty.

Where can we change minmum duty in this program?

Is there any problem if We change the minimum duty?

best regards,

The min duty or actually minimum phase shift in PSFB is dependent on the peak current mode blanking time (PCM_BLANK).
So changing the value of PCM_BLANK may help. But depending on your hardware this value will have a bottom limit and can not be reduced much.
