"Single Feature SizeTM" strip-based process. The
resulting transistor shows the best trade-off be-
tween on-resistance ang 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.
