LM5017: Number K of calcrate for fsw

ACGUY

Part Number: LM5017

Hi all,

Please let me know about calcrate for fsw.
Equation 1 in dataseet, K =9 * 10^(-11).
However, K =10 * 10^(-10) in EVM user's giide.
Which is correct?

It is rounding, they are essentially the same. 9E-11 = 0.9E-10 vs 1 E-10. The usesrs guide just shows 10^-10 without a multiplier (0.9 rounded up to 1).

If you do decision, which do you take?
I hope these will be unified.

I do not support that part directly. As a general rule I would follow the datasheet. You could also split the difference an use 9.5E-10. We are looking at a very small number here.
