WebWhen the high-side MOSFET is turned ON, the transition of the body diode of the low-side MOSFET from the forward direction to the reverse bias state causes a diode recovery, which in turn generates a reverse recovery loss in the body diode. This loss is determined by the reverse recovery time of the diode . WebThe synchronous buck circuit is in widespread use to provide “point of use” high current, low voltage power for CPU’s, chipsets, peripherals etc. In the synchronous buck converter, the power stage has a “high-side” (Q1 below) MOSFET to charge the inductor, and a “Low-side” MOSFET which replaces a conventional buck regulator’s “catch diode” to provide …
