Alpha and Omega Semiconductor Introduces the New Generation PairFET™
Optimized PairFET reduces the temperature rise by 8 degrees C for Vcore power
SUNNYVALE, Calif., Dec. 17, 2015 – 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 introduced the new generation
of high efficiency PairFETs. The AOE6930 is an asymmetric package with integrated high-side and low-side MOSFETs. The
product is designed with AOS's latest silicon technology to optimize the conducting resistance and the switching
characteristics of both MOSFETs in order to attain the highest efficiency over the whole output range when working as the
power stage for a Vcore power supply circuit. The combination of AOS's XSFET™ technology in this new generation
PairFET package, gives the device an extra advantage in thermal dissipation. The device is ideal, but not limited to power
supplies in computing, telecom and high power density point-of-load socket applications.
The latest generation of CPUs requires separate power supply circuits for each Vcore rail, which creates a challenge for the
power supply designers. They have to fit more DC/DC circuits onto almost the same area, and at the same time improve the
total power efficiency. As the most important components of the power stage, MOSFETs with ultra-low on-resistance, lowest
switching loss, and compact yet low thermal resistance packages are essential to meet the design target. AOE6930 integrated
the high-side and the low-side MOSFETs, with 7mOhms and 1.05mOhms maximum on-resistance, respectively, within a
5mm x 6mm DFN package. The low-side MOSFET source is connected directly to the exposed pad, which can easily be
connected to the ground plane in PCB design. This feature provides the circuit designers a significant benefit in enhancing
the thermal dissipation. Test results on an existing notebook PC design, under a typical 19.5V input, and 1.2V 21A output
condition, the device showed over one percentage efficiency improvement, and reduced the temperature rise by 8 degrees C,
in comparison with the current solutions found in the market.
"AOE6930 is the start of a new era of AOS solutions for CPU Vcore power supply circuits. This device is a great
combination of AOS's silicon and packaging technologies, and it's further optimized with our application know-how in this
area. Both the efficiency and thermal performance already showed the advantage over the existing solutions. This device is
not limited to PC applications, it is also a good solution for other high frequency PWM circuit which requires best-in-class
performance in efficiency and thermal design", said Lei Feng, Marketing Director of MOSFET product line at AOS.
