WebSep 16, 2024 · Thank you for your patronage. Why does the high-side switch turn ON with the Buck converter in the figure below? Since the threshold value of the high side switch is 0.5 V, to turn on the high side switch, for example, VG = 10 + 1 V is required as shown below. However, in the simulation circuit, the high side switch is turned on with VG = 1 V.
