Applications
Description
UniFET TM MOSFET is Fairchild Semiconductor ’s high voltage
MOSFET family based on planar stripe and DMOS technology.
This MOSFET is tailored to reduce on-state resistance, and to
provide better switching performance and higher avalanche
energy strength. This device family is suitable for switching
power converter applications such as power factor correction
(PFC), flat panel display (FPD) TV power, ATX and electronic
lamp ballasts.
? LCD/LED/PDP TV
? Lighting
? Uninterruptible Power Supply
