WebSynchronous buck converters, typically used for front end pre-regulation in wide-input DC/DC brick converters, also switch the low-side MOSFET in ZVS mode. While the hard switched bridges and boost converters do not have critical dead time requirements, all soft-switched ZVS bridges and synchronous buck converters must operate within such limits. 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 . troy bridges wkmgWebJul 20, 2010 · Maxim Integrated Products introduces the MAX15054, a high-side MOSFET driver for high voltage applications.
