Hello E2E,
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.
Regards,
ACGUY
