SUNNYVALE, Calif., May 31, 2016 (GLOBE NEWSWIRE) -- Alpha and Omega Semiconductor Limited (AOS) (Nasdaq:AOSL), a designer, developer and global supplier of a broad range of power semiconductors and power ICs, today announced the release of 8 new products in the 60V MOSFET family. These products are designed for synchronous rectification in flyback converters, used in quick chargers for smart phones and other portable devices. The part numbers include AO4262E, AO4264E, AO4268, AON6262E, AON6264E, AON6268, AON7262E, and AON7264E. These products offer three levels of maximum on-resistance at 4.5V gate drive voltage: 6.5mohm, 8.5mohm, 13.5mohm. They are available in three package types: SO-8, DFN5x6, and DFN3x3.

The latest evolution of battery technologies now allows the adoption of higher power charger circuits to power up smart phones and other mobile devices within a shorter time. This drives the demand for higher performance MOSFETs for synchronous rectification. There are two major approaches the industry is taking to realize higher charging power. The first approach is to raise the output voltage of the charger, so that with the same output current, higher power can be delivered to the battery system. Then, the charging management circuit converts the power into the desired charging voltage and current. The second approach is to directly increase the output current of the charger circuit. AOS provides MOSFET solutions for both topologies.
These new products primarily address the second approach of using lower voltage and higher current solutions. This approach utilizes a simple circuit design by keeping high current conversion inside the charger. A 60V platform is selected for better on-resistance and voltage tolerance balance. The entire product family is optimized for low on-resistance at a lower gate drive voltage, which is normally around 4.5V for most controllers. Switching losses are significantly dependent on the control scheme used in the charger circuit. AOS's proprietary AlphaSGTTM process provides best-in-class on-resistance with very low parasitic capacitance, which ensures lower switching loss. The devices are also tuned to keep EMI suppression simple and reliable.
"AOS has been working closely with both smart phone pioneers as well as controller chipset providers in pushing forward the synchronous rectifier solutions for high efficiency chargers. Our application know-how in combination with our leading AlphaSGTTM technology keeps us as the solution leader in this field. The release of these 8 new products provides our customers more flexibility in selecting the right product for their specific designs. In addition to providing wider application coverage, we are offering customers a set of products with the best balance of on-resistance with low EMI emission, thermal dissipation with compactness, and efficiency with cost," said Lei Feng, Sr. Marketing Director of MOSFET product line at AOS.
