DESCRIPTION
This power MOSFET is designed using the
company’sconsolidated strip layout-basedMESH
OVERLAY process. This technology matches
and improves the performances compared with
standardparts from various sources.
APPLICATIONS
■ HIGH CURRENTSWITCHING
■ UNINTERRUPTIBLE POWER SUPPLY(UPS)
■ DC/DC COVERTERSFOR TELECOM,
INDUSTRIAL, AND LIGHTINGEQUIPMENT.
