DESCRIPTION
The FDmeshTM associates all advantages of reduced INTERNAL SCHEMATIC DIAGRAM
on-resistance and fast switching with an intrinsic fast-
recovery body diode. It is therefore strongly recom-
mended for bridge topologies, in particular ZVS phase-
shift converters.
APPLICATIONS
s ZVS PHASE-SHIFT FULL BRIDGE CONVERTERS
FOR SMPS AND WELDING EQUIPMENT
