DESCRIPTION

This application specific Power Mosfet is the third

generation of STMicroelectronics unique ”Single

Feature Size

™” strip-based process. The resul-

ting 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.
