Description
This application specific Power MOSFET is the third genaration 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 performance in terms of both conduction and switching losses. This is extremely important for motherboards where fast switching and high efficiency are of paramount importance.
