UCC28950: How to decide delay time and how to work in CS, ADEL and ADELEF of UCC28950

Part Number:UCC28950

Dear TI member,

We have questions of UCC28950

1. How to check CS, ADEL and ADELEF voltage for delay time? (Vrms? Vpeak? or other point?)

=>Please help to teach us how to check the voltage for delay time.

2. If Duty is only changed, how do CS and ADEL change ? And delay time also chage? (Peak voltage of CS is not changed. And RAB and KA don't change also.)

If delay time is changed by changing Duty, Please teach us why the delay time change.

If we don't change RAB and KA, TABSET (delay time) depend on CS voltage from UCC28950 datasheet.

We changed only duty on our module and CS peak voltage keep same valtage. But the delay time is changed then.

So we want to know whether Duty affect the delay time. (We want to know why the delay time is changed.)

Thanks
