Alpha and Omega Semiconductor Introduces the Newest Generation 25V Technology in XSPairFET Package

Alpha & Omega » AONX38168

Optimal power efficiency using the latest technology sets a new industry standard for high power density applications

Alpha and Omega Semiconductor introduced the AONX38168, which utilizes the latest 25 V N-Channel MOSFET Technology. The XSPairFET includes the low-side and high-side MOSFET in a leadless surface mount package, (5 mm × 6 mm outline) ideal for synchronous DC/DC converter applications.

Alpha & Omega - AONX38168

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 (RDS(ON) × QG). The XSPairFET has bottom source connection for the low-side MOSFET which can result in improved thermal performance, simplified layout, and reduced EMI.
