WebThe DC/DC buck converter has two main loops where high AC currents flow as shown in figure 2. When the high-side MOSFET Q1 is on, the current flows from supply via Q1 and L1 to the output capacitor and the load. The current flows back via ground to the input. The AC portion of the current will flow via the input and output capacitors.
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.
