Hello TI,
A. Kindly reply to the related thread https://e2e.ti.com/support/power-management/f/196/t/783364
B. LM5017 flybuck transformer xlsx, Air gap calculation Cells I29 & I33, use complex equation comprising of Centre leg length (a), width (b) and le/μe ratio.
Rectangular center leg equation "I31*I32/2*(1/I26-(I31+I32)/I31/I32-SQRT(((I31+I32)/I31/I32-1/I26)^2-4/I31/I32))" translates into
and round center leg equation uses diameter in place of length and width I28^2/2*(1/I26-2/I28-SQRT(1/I26^2-4/I26/I28))
Please share document link for above complex equation
