DESCRIPTION
This application specific Power MOSFET is the
third genaration of STMicroelectronics unique "
Single Feature Size" strip-based process. The re-
sulting transistor shows the best trade-off between INTERNAL SCHEMATIC DIAGRAM
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 effi-
ciency are of paramount importance.
