Hello

Some question regarding the design

1. Any specific document reference for voltage compensation apart from SLUC222C excel file.

2. When no shim inductor is used, how to calculate tank frequency?because my design does not recommend shim inductor

Hello Suresh,

Thank you for your interest in UCC28951.

May I refer you to the resource page of the TI power supply design seminar available at the link below:

When using a TL431 in the feedback loop then Han and Ye article at www.ti.com/.../slua671.pdf provides useful information.

I would clarify the Shim inductance calculation for you and get back by Monday next week.

Regards,

Sonal

Hello Suresh,

Please use the value of the leakage inductance of your transformer in calculations where shim inductance is mentioned.

Sonal
