Alpha and Omega Semiconductor Announces XSPairFET™ Buck-Boost MOSFET for Higher Power USB PD 3.1 EPR Applications
Alpha and Omega Semiconductor (AOS) introduces AONZ66412 XSPairFET™ MOSFET for Buck-Boost converters in USB PD 3.1 EPR applications. The product offers high efficiency, compact design, and improved power density, catering to the Type-C performance demands.
The introduction of the AONZ66412 XSPairFET™ by Alpha and Omega Semiconductor Limited represents a noteworthy advancement in power semiconductor technology. This development is particularly significant for the design of power conversion systems in portable electronics. The AONZ66412's compact footprint and high-efficiency capabilities are a response to the increasing demand for more power-dense solutions in smaller form factors.
From an electrical engineering standpoint, the integration of two 40V N-Channel MOSFETs in a half-bridge configuration within a single package is a technical achievement that can lead to reduced parasitic inductance and switch node ringing, which are common challenges in high-frequency power conversion. The direct connection of the low-side MOSFET source to the lead frame enhances thermal performance, allowing for higher power handling and reliability. The capability to operate at 1MHz further allows designers to use smaller inductors, contributing to the overall reduction in size and cost of the power supply design.
From a supply chain perspective, the 16-week lead time for the AONZ66412 indicates a relatively stable production and delivery schedule, which is important for manufacturers planning their product development cycles. The pricing point of $1.56 per unit in 1,000-piece quantities suggests competitive positioning within the market, potentially influencing the procurement strategies of OEMs and ODMs in the consumer electronics sector.
Moreover, the ability of the AONZ66412 to replace two single DFN5x6 MOSFETs not only simplifies the production process but also reduces the complexity of inventory management for manufacturers. This simplification could lead to more efficient logistics and potentially lower costs in the long term, which can be a significant factor when companies are deciding on the components for new designs.
The release of the AONZ66412 XSPairFET™ aligns with the observed market trend towards USB PD 3.1 Extended Power Range (EPR) applications. As devices increasingly require higher power delivery over USB-C, the demand for components that can support these specifications is expected to grow. This MOSFET is positioned to cater to this emerging market segment, potentially capturing a significant share due to its high-efficiency performance and power density improvements.
Given that USB PD 3.1 EPR is set to become the new standard for a wide range of consumer electronics, including notebooks and power banks, the AONZ66412's optimized design for these applications could make it a preferred choice for manufacturers. The potential for increased adoption of the AONZ66412 could have a positive impact on AOS's market presence and financial performance, making it a company to watch for stakeholders in the semiconductor and consumer electronics industries.

Offering a compact footprint to streamline PCB design, the AONZ66412 XSPairFET™ helps improve power density while meeting high-efficiency Type C performance demands
SUNNYVALE, Calif. --(BUSINESS WIRE)--
Alpha and Omega Semiconductor Limited (AOS) (Nasdaq: AOSL), a designer, developer, and global supplier of a broad range of discrete power devices, wide bandgap power devices, power management ICs, and modules, today announced its AONZ66412 XSPairFET™ MOSFET designed for Buck-Boost converters in USB PD 3.1 Extended Power Range (EPR) applications. The USB PD 3.1 EPR increases the USB-C maximum power up to 240W. AONZ66412 is defined to support the most commonly addressed power range of up to 140W at 28V, with two 40V N-Channel MOSFETs in a half-bridge configuration in a symmetric XSPairFET™ 5mmx6mm package.

The AONZ66412 can replace two single DFN5x6 MOSFETs, reducing the PCB area and simplifying the layout of the 4-switch buck-boost architecture while enabling a higher efficiency design. These benefits make the AONZ66412 ideal for buck-boost converters in Type-C USB 3.1 EPR applications, including notebook, USB hub, and power bank designs.
The AONZ66412 is an extension to the AOS XSPairFET™ lineup that features the latest bottom source packaging technology and lower parasitic inductance for reduced switch node ringing. Engineered with integrated high-side and low-side MOSFETs (3.8mOhms maximum on-resistance for each FET) within a DFN5x6 symmetric XSPairFET™ package, the low-side MOSFET source of the AONZ66412 is connected directly to a large paddle on the lead frame. This allows for improved thermals, as this paddle can be directly connected to the ground plane on the PCB. The improved package parasitics make 1MHz operation achievable, allowing inductor size and height to be reduced. AONZ66412 has been tested to achieve 97% efficiency @1MHz in typical USB PD 3.1 EPR conditions of 28V input, 17.6V output, and 8A load conditions.
“AOS specifically designed the AONZ66412 to meet EPR Type C PD application demands. AONZ66412 will reduce board space and improve power density to achieve the high-efficiency performance goals designers have set for this widely adopted USB-PD Type C application. AOS continues to be a leading innovator of buck-boost architecture solutions,” said Rack Tsai, Marketing Director of MOSFET product line at AOS.
