The output stage has the capacity drive up to 2.0 A peak into an isolation transformer or simple coil coupling to the mains.

At an output current of 1.5 A, the output voltage is guaranteed to swing within 1.0 V or less on either rail, ensuring optimal signal-to-noise ratio (SNR) in harsh environments. The NCS5650 draws just 150 µA while in shutdown mode. Power supply options are single-sided 6 V to 12 V and dual balanced ±3.0 V to ±6.0 V.

With its unique full power bandwidth, the NCS5650 can operate in any region of the world while complying with local PLC frequency band regulations like CENELEC.

The devices have an extended junction temperature range of −40 °C to +125 °C. They are offered in a compact QFN package with an exposed thermal pad for enhanced heat dissipation and increased thermal reliability which provides cost sensitive designers a further bill of materials cost reduction.

The NCS5650 is offered in a compact 20-pin, 4 mm x 4 mm x 1 mm, Pb-free, QFN package priced at $3.73 per unit in 10,000 unit quantities.

“The advent of power line communications allows utility companies to add greater levels of functionality to their electricity distribution networks - thereby providing consumers more control over their energy consumption,” said Simon Keeton, general manager of ON Semiconductor’s Audio, Video and Interface products division.

“When combined with an industry leading Spaced Frequency Shift Keying (SFSK) modem, like ON Semiconductor’s AMIS-49587, the NCS5650 acts as an adaptive solution for PLC communications with a desirable balance of performance and price. Designs employing this solution will benefit from high levels of integration which provides a reduced component count and a decreased overall bill of materials.”

Component shortages hurdle to recovery

JOHANNESBURG, SOUTH AFRICA: Stockcall.com offers investors comprehensive research on the printed circuit boards industry and has completed analytical research on Flextronics International Ltd and Celestica Inc.

Electronics Manufacturers were poised for a bounce back year but component shortages have slowed down the recovery. The shortage of components has adversely affected the electronics production chain. Essentially, electronics manufacturers were producing at a high rate due to the recent spike in global computer and mobile phone demand. However, a shortage in components, namely semiconductors, is negatively impacting recovery and growth.

Raw materials shortages also created difficulties. Manufacturers produced at a rate to meet demand but when the production chain was interrupted, many manufacturers saw a decline in profits and an increase in issues related to being overstocked. Visit www.stockcall.com/ to see how companies in this industry have grown over the past years and how they are expected to perform in the future.

There is reason for optimism though as efforts are underway to correct the components shortage issues. Already narrow operating margins will continue being put into increased peril while the production chain slowly corrects itself. In the meantime, many electronics manufacturers will try to weather the storm until production returns to rates prior to the shortages.

Traction battery market to exceed $55 billion by 2020

ROCKVILLE, USA: MarketResearch.com has announced the addition of IDTechEx Ltd's new report "Electric Vehicle Traction Batteries 2010-2020" to its collection of Energy market reports.

Rapidly growing market for traction batteries will exceed $55 billion in only ten years. However that spans battery sets up to $500,000 each with great sophistication needed for military, marine, and solar aircraft use.

Huge numbers of low cost batteries are being used for e-bikes but even here several new technologies are appearing. The largest replacement market is for e-bikes today and the value market for replacement batteries will not be dominated by cars when these batteries last the life of the car -- something likely to happen within ten years. The trends are therefore complex and that is why IDTechEx has analyzed them with great care.

Vehicle manufacturers are often employing new battery technology first in their forklifts or e-bikes, not cars, yet there is huge progress with car batteries as well -- indeed oversupply is probable in this sector at some stage. The mix is changing too. The second largest volume of electric vehicles being made in 2010 is mobility aids for the disabled but in ten years time it will be hybrid cars.

The market for car traction batteries will be larger than the others but there will only be room for six or so winners in car batteries and other suppliers and users will need to dominate their own niches to achieve enduring growth and profits.

This report analyzes the successes, the needs, the statistics and the market potential for traction batteries for all the major applications. It is important to look at the whole picture because traction battery manufacturers typically sell horizontally across many applications and electric vehicle manufacturers increasingly make versions for many applications.
