t(s)Description
ucThis series of devices is realized with the second
dgeneration of MDmesh™ technology. This
rorevolutionary Power MOSFET associates a new
Pvertical structure to the company’s strip layout to
teyield one of the world’s lowest on-resistance and
gate charge. It is therefore suitable for the most
Obsoledemanding high efficiency converters.
