DESCRIPTION

This application specific Power MOSFET is the

third genaration of STMicroelectronis unique "Sin-

gle Feature Size™" strip-based process. The re-

sulting 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 effi-

ciency are of paramount importance.
