The TPA3113D2 is a 6-W (per channel) efficient, Class-D audio power amplifier for driving bridged-tied stereo speakers. Advanced EMI Suppression Technology enables the use of inexpensive ferrite bead filters at the outputs while meeting EMC requirements. SpeakerGuard™ speaker protection circuitry includes an adjustable power limiter and a DC detection circuit. The adjustable power limiter allows the user to set a ''virtual'' voltage rail lower than the chip supply to limit the amount of current through the speaker. The DC detect circuit measures the frequency and amplitude of the PWM signal and shuts off the output stage if the input capacitors are damaged or shorts exist on the inputs.

In all possible industrial, military and household/personal applications, the number of digital devices operating with data rates of hundreds of Megabits, using processor chips with Gigahertz clocks, has increased astronomically. At the same time, a myriad of popular RF receivers like portable telephones, laptop PCs with integrated wireless modems, wireless Internet, and other electronic devices, are becoming ubiquitous, such that the number of sensitive, licit receivers operating within a square kilometer of an urban area can be counted in tens of thousands. In the crowded space that they share, the conjunction of both events is increasing the number of potential interference situations, especially in the upper VHF and UHF regions where spurious radiations are most difficult to contain. There is, in addition, a growing, although controversial, concern about the possible health hazard caused by long exposure to near fields of low power radio transmitters. All these aspects result in a continuous effort for lowering RF radiations.This new edition of Controlling Radiated Emissions by Design retains the step-by-step approach for incorporating EMC into every new design, from the ground up. Quite different from other classical EMC books, it approaches the problem from a development engineer's viewpoint, starting with the selection of quieter IC technologies, their implementation into a noise-free printed circuit layout, and the gathering of all these into a low radiation packaging, including I/O filtering, connectors and cables considerations. Equally far from a cookbook of recipes, all guidelines are supported by thorough, but relatively easy and comprehensive calculated examples, allowing a quantitative design, instead of purely qualitative. New to this edition is material on surface mount techniques, IC's ground-bounce, random-versus-periodic frequency spectra and recent progress in low cost ferrite and filter components. Also included is detailed information on radiation from high-speed chips (e.g. Pentium 200 MHz) and the efforts by some manufacturers to reduce it. The book has numerous tables, all of which have been updated to reflect the latest changes in the field, including a brief overview of the U.S. and worldwide emission tests.Controlling Radiated Emissions by Design is an invaluable tool for helping design engineers, EMC specialists and technicians develop more efficient and economical control of emissions.
The 3rd edition of Controlling Radiated Emissions by Design has been updated to reflect the latest changes in the field. New to this edition is material on aspects of technical advance, specifically long term energy efficiency, energy saving, RF pollution control, etc. This book retains the step-by-step approach for incorporating EMC into every new design, from the ground up. It describes the selection of quieter IC technologies, their implementation into a noise-free printed circuit layout, and the gathering of all these into low radiation packaging, including I/O filtering, connectors and cables considerations. All guidelines are supported by thorough and comprehensive calculated examples. Design engineers, EMC specialists and technicians will benefit from learning about the development of more efficient and economical control of emissions.
EMC has become a major concern in the development of electronic devices due to high comfort and safety standards. In the scope of EMC engineering, the simulation has grown in the last years to an indispensable tool as it allows reducing development time and resources. This interest has increased the demand on model accuracy which ramped up model complexity and computation time. Improving the underlying computational methods is thus of great importance for a better efficiency of EMC simulation.Model order reduction (MOR) has been implemented in this work in a concept from EMC computation (prediction) through EMC analysis to EMC optimization for a better integration of EMC simulation in the development process of electronic components. The efficiency of this concept has been showed on real-life problems.
Sea Sonic Electronics launches the M12II “Bronze” Series, the new and upgraded version of the M12II “Bronze” Series in response to the growing demand and anticipation for more energy-efficient products. The M12II Bronze Series inherits the same output and wattage options as well as the superb quality and ultimate silence from the M12II Series. The M12II, available in 500 watts, offers buyers with a mid range power output solution with cable management, to meet their exact system needs, cable management is now made easier than ever.The M12II Bronze Series achieves the 80 PLUS® Bronze standard of at least 82%, 85% and 82% efficiency under 20%, 50% and 100% operating loads respectively. Combined with Active Power Factor correction (Active PFC), the M12II Bronze reduces energy waste, boosts power efficiency and more importantly, helps the users to save energy and reduce electricity bill.While upgrading in efficiency, the M12II Bronze Series maintains the advanced designs and quality components from the past M12II line. Such designs and components including Double Forward Converter design, Smart and Silent Fan Control and highly reliable Japanese brand capacitor also boost the overall performance in stability and silence. The M12II Bronze Series is available in standard ATX Form Factor and in wattages that are beneficial for a PC system. With the all-in-one cabling design and EPS connectors, the M12II Bronze Series is geared to support IPC and server systems and as well, both 6P & 8P PCI-E connector for latest and high end dual graphic cards. Moreover, the modular design also provides a flexible solution for orderly cable management.The M12II Bronze Series is made reliable by featuring safety regulations such as Over Voltage Protection (OVP), Short Circuit Protection (SCP), and Over Power Protection (OPP). Major safety and EMC directives and as well, the environmental certifications RoHS and WEEE increase safety and usage reliability for the users.
