Part Number: TPS54360
I tried to calculation VBOOT, result was negative value.
Vin=32V, Vf=0.52V, fsw=130kHz, IB2SW=100uA.->VBOOT= - 0.5196V.
Maybe, I do not understand the formula exactly.Do you know the same case or question?
About Fig.1, VB2SW are 3V and 6V.Please let me know about condition for operating.
I have try to calculate equation 2 according to your input condition and i get a VBOOT value of 4.43V.
Do you convert the 130kHz to MHz? Also for figure 1, this data could come from a tester with open loop condition with test mode to measure Rdson.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Arief Hernadi:
The conversion from kHz to MHz is still correct. However, there was one small miscalculation with tsw. Here is the revised version.
