5-Watt DC-DC Converter Boasts Cold Start Up of -55°C
Aimtec's new 5W dc-dc converters series, AM5E-FZ,operates at -55°C to +85°C, without derating, to support all outdoor applications, including those at risk of being exposed to severe temperature conditions. Such applications include solar inverters, smart meters, transmission equipment, security systems, traffic and advertising signage.

Outdoor temperatures in more than 24 regions across Europe and North America have been known to drop to below -45°C. Under such conditions, many outdoor applications fail simply because one or more of their internal components are not designed to operate at below -45°C.
AM5E-FZ series offers 21 models with a choice of wide, 2:1 input ranging from 9 to 72Vdc, stepping down to single or dual output ranges of 3.3 to 15Vdc, at efficiency rates as high as 87%. Design engineers will also appreciate the tight line and load regulation of 0.5% (single output models), as it ensures that stable voltages are delivered throughout the operating range, under all loading conditions.

With a fixed switching frequency of 300kHz, designs using the AM5E-FZ series benefit from a simplified filter design process, which also translates to smaller, more compact filters — an important consideration for many applications.
Other design value features include I/O isolation of 1.5kVdc, continuous short circuit protection, over load and voltage protection, all housed in a compact 2"x1" case which stands only 0.40" high. Samples are available from stock.

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.
