Alpha and Omega Semiconductor 475 Oakmead Parkway, Sunnyvale, California 94085 USA FOR IMMEDIATE RELEASE Media Contact: Martha Aparicio Tel: 408.789.3233 Email: [email protected] Alpha and Omega Semiconductor Rolls Out New Family of 25V and 30V High Performance MOSFETs in Compact 3x3mm Footprint Helping designers achieve high efficiency DC/DC conversion for high switching frequency applications SUNNYVALE, Calif., July 2, 2014 – 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 six new 25V and 30V MOSFETs (AON7760, AON7510, AON7758, AON7764, AON7536, and AON7538), the latest additions to the low voltage portfolio in compact 3 x 3mm DFN packages. These devices are ideally suited for a variety of DC/DC step-down conversion solutions for personal computing, gaming, servers, and telecom/datacom applications. The new devices use AOS’s proprietary power trench MOSFET technology to accomplish an exceptionally low figure-ofmerit (RDS(ON) x Qg) for fast switching applications such as the latest DC/DC converters that operate over 600KHz. The AON7536 is optimized for high-side switching by minimizing Qg and Crss, thus, lowering the switching power losses. When paired with the AON7760, AON7536 can achieve 90% efficiency at 15A for a 12V input and 1.8V output. This new 3x3 DFN family has a 20% figure-of-merit improvement from the previous generation. While keeping the same on-resistance, designers can enjoy the 20% lower Qg to operate at a higher switching frequency. In addition to the DC/DC applications, the AON7510’s ultra low RDS(ON) 1.3mΩ (max) @ 10V is ideal for conduction loss critical applications such as those with a high current system switch, load switch, or motor drive. “Whether the designs are fast switching or turn-on/off applications, AOS’s new DFN 3x3mm MOSFETs are able to minimize both switching and conduction loss for a cooler and more efficient operation in a common industry footprint.” said George Feng, Senior Manager of Product Marketing. AON7760, AON7510, AON7758, AON7764, AON7536, and AON7538 are all Halogen-Free and RoHS compliant.
