This paper presents the modeling results for prediction of thermal performance using synthetic jets ejectors. A synthetic jet is an intense, small-scale turbulent jet synthesized directly from the fluid in which it is embedded. A jet ejector consists of a primary high momentum jet inducing a secondary flow within a channel....

Battery life is getting increased scrutiny as our devices continue to shrink but are still expected to deliver more functionality and performance than ever before. Effectively extending battery life in future devices will require mastery of low quiescent current. This paper examines the role of low quiescent current in...
Bluetooth® Low Energy (BLE) may not be part of your electronic designs just yet, but chances are it will be soon. This wireless connectivity technology has experienced explosive growth over the last three years. And it now provides low-power connectivity to millions of electronic devices, such as smart watches, fitness...
When transitioning from a traditional phone network to a voice over IP (VoIP) network, it is essential to recognize a key difference between the public switched telephone network (PSTN) and the private data network that will be called upon to take its place.
The PSTN is connected to a massive battery array that allows...
Field-programmable gate arrays (FPGAs) have gained much attention and widespread application in the end market. This document outlines the requirements for FPGA power supply and related issues.
It will also discuss the latest digital power module from Renesas, which can be used as a power supply solution for FPGA...
Digital power is one of the most important technologies for reducing power consumption and managing the growing power complexity in modern electronic systems.
This paper explores the many benefits for system designers working with digital power modules, and shows how digital power modules can simplify the design of...
Racks organize IT equipment, such as servers and network switches, into standardized assemblies that make efficient use of space and other resources. Depending on the options you choose, they can also improve power protection, cooling, cable management, device management, physical security, mobility, ease of installation...
One of the fundamental decisions in the design of data centers, server rooms and network closets is which uninterruptible power supply (UPS) systems to use.
You cannot be certain that the power you receive from your local utility will be suitable for your equipment, or that it will always be available. And even when...
Every type of electronic equipment – from PCs, servers and network equipment, to home theaters, computer peripherals and mobile devices – is vulnerable to damage caused by power surges and line noise interference. With a relatively modest investment, surge protectors offer a highly effective way to protect...
The reliability of communications equipment depends primarily upon the reliability of the power supply. The most cost-effective approach to power system design is to employ power supplies designed for the application.
Power supplies that dissipate heat from the sensitive electronics via large, flat baseplates to heatsinks...
