AON7458
250V,5A N-Channel MOSFET
General Description
The AON7458 is fabricated using an advanced high voltage MOSFET process that is designed to deliver high levels of
performance and robustness in popular AC-DC applications.By providing low R
DS(on)
, C
iss
and C
rss
along with
guaranteed avalanche capability this device can beadopted quickly into new and existing offline power supply
designs.This device is ideal for boost converters and synchronous rectifiers for consumer, telecom, industrial
power supplies and LED backlighting.
