Why does the high-side switch turn ON with the Buck converter in …

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. Websynchronous buck converter, the change in inductor current during the high side MOSFET on−time is equal to the change during the high side MOSFET off−time. In other words, the inductor current increase is equal to the inductor current decrease (refer to Figure 2). I L( ) L( ) (eq. 3) For this reason, the inductor current ripple can simply be
