Internal schematic diagram Description 4 OR These devices are N-channel Power MOSFETs developed using the second generation of MDmesh technology. This revolutionary Power MOSFET associates a vertical structure to the companys strip layout to yield one of the worlds lowest on-resistance and gate charge. It is therefore suitable for the most demanding high efficiency converters. 3 - V Table 1.
