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 between on-re-
sistance and gate charge. When used as high and           INTERNAL SCHEMATIC DIAGRAM
low side in buck regulators, it gives the best perfor-
mance in terms of both conduction and switching
losses. This is extremely important for mother-
boards where fast switching and high efficiency are
of paramount importance.



APPLICATIONS
s SPECIFICALLY DESIGNED AND OPTIMISED
  FOR HIGH EFFICIENCY CPU CORE DC/DC
  CONVERTERS
