High side buck converter

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 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.
