DESCRIPTION
Using the latest high voltage MESH OVERLAY™
process, STMicroelectronics has designed an advanced family of power MOSFETs with outstanding
performance. The new patented STrip layout coupled with the Company’s proprietary edge termination structure, makes it suitable in coverters for
lighting applications.
APPLICATIONS
■ HIGH CURRENT, HIGH SPEED SWITCHING
■ SWITH MODE POWER SUPPLI ES ( SMPS)
■ DC-DC CONVERTERS FOR TELECOM,
INDUSTRIAL, AND LIGHTING EQUIPMENT
