DESCRIPTION
This application specific 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 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.
