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 WebJun 14, 2024 · In an actual device using NMOS high-side FETs there's a trick to dealing with this issue: use a bootstrap voltage generator to make the high-side gate driver supply. …
