SUNNYVALE, CALIF.--(BUSINESS WIRE)--
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 AOZ6662DI-01 and AOZ6663DI-01, high efficiency, simple-to-use synchronous buck regulators. The AOZ6662DI-01 and AOZ6663DI-01 are both available in a thermally enhanced DFN3x3 exposed pad package, delivering an output current of 2A and 3A, respectively. The new devices offer a low on-resistant power stage, 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 these devices allows higher efficiency and less heat generation. They have over 90 percent efficiency at full load operation and maintain at 87 percent efficiency while in 10mA light load operation. When operating in low output current conditions, the device will run in a proprietary pulse energy mode (PEM) to obtain high efficiency. Under heavy load steady-state conditions, the device will operate in a fixed frequency and Continuous-Conduction Mode (CCM).
The small standby current combined with a thermally enhanced package achieves better efficiency and thermal performance over the previous generation solution and leading competitor.
“Today’s consumer electronics products are built with features that require flexibility to meet a broad range of applications. Design engineers are looking for dc-dc converters that offer high light load efficiency at specific voltage ranges,” said Kenny Hu, Power IC Marketing Manager at AOS. “The AOZ6662DI-01 and AOZ6663DI-01 meet these design challenges with adaptable light load capability.”
