Description
This application specific Power MOSFET is the
third generation of STMicroelectronics unique
"single feature sizeTM" strip-based process. The
resulting transistor shows the best trade-off          Internal schematic diagram
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. remarkable manufacturing
reproducibility.
