DESCRIPTION
This application specific Power MOSFET is the
third genarat ion of STMicroelectronics unique
“Single Feature Size
™” strip-based process. The
resulting transistor sho ws the best trade-off between on-res istance ang gate charge. When used
as high and low side in buck regulators, it gives the
best perfo rmance in terms of both conduction and
switching losses. This is extremely important for
motherboards where fast switching and high efficiency are of paramount impo rtance.
