UCC28950: Lmag

Part Number: UCC28950

Hi TI,

I have several questions as below.

1. Why Equation-30 for Lmag is with (1-Dtyp)? Should it be Dtyp? Because the Lmag current conduct during Dtyp.

2. Is it acceptable that the Lmag designed is 3.54mH while the min value calculated from Equation-30 is 17mH? It is not feasible to meet this at variable output conditions while having low winding loss of transformer.

Regards,

KK
