The AONX38168 is designed with the latest bottom source packaging
technology which has a lower switch node ringing due to lower parasitic
inductance. The new device offers a higher power density comparative to
existing solutions, and is well suited for server and telecommunication
markets. The AONX38168 is the newest generation of XSPairFETs, offering
the lowest on-state resistance and best Figure of Merits (Rdson x Qg).
The XSPairFET has bottom source connection for the low-side MOSFET which
can result in improved thermal performance, simplified layout, and
reduced EMI.

"With the significant performance improvement, the AONX38168 allows new
designs to operate at higher switching frequencies. In addition, AOS can
offer a complete solution with Digital Power and Power IC products for
DC/DC voltage regulation for demanding applications in server and
telecommunications," said Peter H. Wilson, Marketing Director of MOSFET
product line at AOS.
