## **Application** Switching applications ## **Description** These devices are made using the second generation of MDmesh™ technology. This revolutionary Power MOSFET associates a new vertical structure to the company’s strip layout to yield one of the world’s lowest on-resistance and gate charge. It is therefore suitable for the most demanding high efficiency converters. ## **Figure 1.
