SUNNYVALE, Calif., Dec. 23, 2015 (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 the AOZ3101, a high efficiency, simple-to-use synchronous buck regulator, with an operating input voltage range from 4.5V to 18V, supplying 2A of continuous current. The device offers a low on-resistant power stage in a thermally enhanced 3mm x 3mm DFN package, allowing cooler power conversion for a variety of consumer electronics application such as LCD TVs, set-top boxes, as well as DVD players and recorders.

The low on-resistance of the internal power MOSFETs in this device allows higher efficiency and less heat generation. It has over 90 percent efficiency at full load operation and maintains it at 85 percent efficiency while in 10mA light load operation. When operating in low output current conditions, the device will operate in a proprietary pulse energy mode (PEM) to obtain high efficiency. Under heavy load steady-state conditions, the device will operate in fixed frequency and Continuous-Conduction Mode (CCM).
The full load efficiency of the AOZ3101 is 1 percent higher and the IC surface temperature is almost 30 percent lower than that of the closest competitor.
“We continue to expand our fifth generation EZBuck product portfolio to provide our customers with higher efficiency and more reliable DC/DC solutions,” said Kenny Hu, Power IC Product Marketing Manager at AOS.
