DESCRIPTION
This applicationspecific Power Mosfet is the third generation of STMicroelectronics unique ”Single Feature Size” strip-based process. The resul­ting transistor shows the best trade-off between on-resistance and gate charge. When used as high and low side in buck regulators, it gives the best performancein termsof both conductionand switching losses. This is extremely important for motherboardswhere fast switching and high effi­ciencyare of paramount importance.
