AOS Launches EZBuck With Enhanced Light Load Operation
Alpha and Omega Semiconductor Limited (AOS) released the AOZ3015, a 3A EZBuck™ dc-dc regulator optimized for applications that have a standby power mode. The AOZ3015 is suited for point-of-load dc-dc converters, LCD TVs, set-top boxes, DVD and Blu-ray players/recorders and cable modems. The AOZ3015 is a high-efficiency and easy-to-use synchronous PWM buck regulator with an input voltage range of 4.5V to 18V.

It provides 3A of continuous output current at over 90% efficiency and maintains 85% efficiency while in 10mA light load operation. When operating in low output current conditions, the AOZ3015 will operate in a proprietary pulse energy mode (PEM) to obtain high efficiency. Under heavy load steady-state conditions, the AOZ3015 will operate in fixed frequency and Continuous-Conduction Mode (CCM).
"AOS's proprietary EZBuck technology helps bring our customers compact and high efficiency DC/DC solutions that we can scale to their power requirements," said Dr. Yenju Wang, Product Marketing Director at AOS. "The high-efficiency light load operation feature AOZ3015 makes it an ideal for those power supplies with a stand-by mode mandated by many government agencies worldwide."

The AOZ3015 is immediately available in production quantities with a
lead-time of 12 weeks. The unit price for 1,000 pieces is $0.80.

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
