Internal schematic diagram Application Switching applications Description The FDmesh associates all advantages of reduced on-resistance and fast switching with an intrinsic fast-recovery body diode. It is therefore strongly recommended for bridge topologies, in particular ZVS phase-shift converters. Table 1.
