25V technology in XSPairFET package has low rds on for power density

Designed for the server and telecommunications markets, the AONX38168 is the latest generation of XSPairFET from Alpha and Omega Semiconductor (AOS).

The AONX38168 uses the latest 25V n-channel MOSFET technology and includes the low-side and high-side MOSFET in a leadless surface mount package. Measuring 5.0 x 6.0mm outline, it is suitable for synchronous DC/DC converter applications.

The AONX38168 is designed with the latest bottom source packaging technology, explains AOS, which has a lower switch node ringing due to lower parasitic inductance. It offers a higher power density comparative to existing solutions, says the company, with 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, adds AOS.

“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, MOSFET product line at AOS.

The AONX38168 is immediately available in production quantities with a lead-time of 12 to 14 weeks.

AOS designs, develops and supplies a broad range of power semiconductors, including a wide portfolio of power MOSFET, IGBT, IPM, Power IC and digital power products. AOS has developed intellectual property and technical knowledge to address the increasingly complex power requirements of advanced electronics. AOS integrates its discrete and IC semiconductor process technology, product design, and advanced packaging expertise to develop high performance power management solutions. AOS’ portfolio of products targets high-volume applications, including portable computers, flat panel TVs, LED lighting, smart phones, battery packs, consumer and industrial motor controls and power supplies for TVs, computers, servers and telecommunications equipment.
