50: GE Energy Delivers First 300W Eighth Brick Bus Converter

GE Energy is launching a power electronics industry first with the availability of a new eighth brick Barracuda™ series 300W fully regulated digital bus converter. Developed through collaboration with leading technology sector original equipment manufacturers (OEMs), the new dc-dc isolated power modules are the result of a 14-month, $1.1 million technology investment by GE in advanced dc power converter technology and associated software-based digital control.

The new Barracuda series of fully regulated digital bus converters help power innovation in OEM new product designs, while reducing risks, accelerating time to market and lowering costs. The Barracuda series is a drop-in replacement for unregulated and semi-regulated bus converters challenged by recent industry-wide intellectual property issues. The standards-based DOSA footprints and analog/digital compatibility with existing circuit board designs shrinks the size, lowers the cost and improves the performance of dc-dc converter modules.

49: iWatt PrimAccurate Controller Platform Enables Smaller, Greener Power Adapters Up to 40W

iWatt Inc. debuted its newest PrimAccurate™ controller platform. The new iW1699 and iW1760 digital pulse width modulation (PWM) controllers allow power adapter designers to meet stringent emerging global energy regulations for ac-dc power adapters, which require them to consume less than 100mW standby power, with the added benefits of a lower BOM (bill of materials) cost, and smaller overall adapter size.

The iW1699 is optimized for applications up to 12W with ultra-low standby power of less than 30mW to address the needs of smart phone and media tablet applications. The iW1760 is designed for applications requiring higher power, up to 40W, with less than 50mW standby power, including set top boxes, home networking devices, and a wide range of household appliances.

47: Analog Devices Introduces Highly Integrated Synchronous Regulator

Analog Devices, Inc. (ADI) introduced the ADP2164, a 6.5V, 4A output dc-dc regulator featuring a high conversion efficiency of greater than 96 percent. The highly integrated ADP2164 regulator offers an input voltage supply range of 2.7 to 6.5V, an output range as low as 0.6 V and includes low on-resistance switching FETs to maximize efficiency while reducing board space. The ADP2164 provides very high efficiency in a compact 4 x 4mm QFN 16-lead package. This new dc-dc regulator is designed for multi-rail, point-of-load applications ranging from communication infrastructure to industrial devices that demand small size, fast transient performance and highly accurate voltage regulation. Unlike other 5V regulators, the maximum input range of the ADP2164 is 6.5V, which provides additional safety headroom.

44: Curiosity Rover Features Unique Hybrid Power System

NASA's Mars Science Laboratory mission, which is scheduled to land August 5, has the potential to be the most productive Mars surface mission in history. That's due in part to its advanced "hybrid" power system. Space applications are frequently powered by a combination of energy sources — usually solar array/battery combinations. This is the first time a radioisotope thermoelectric generator (RTG), Li-ion batteries and a solar array have been used on the same power system which has to function over all three stages of the mission, cruise, descent and rover.

43: EPC Publishes First Application-focused Gallium Nitride (GaN) Transistors Textbook

Efficient Power Conversion Corp. (EPC) announced the publication of a textbook designed to provide power system design engineers basic technical and application-focused information on how to design more efficient power conversion systems using gallium nitride-based transistors.

According to Alex Lidow, Efficient Power Conversion CEO and co-author of this book, "Gallium nitride transistors provide a long-awaited displacement technology for MOSFETs, and much has been learned over the past several years about how to apply this new technology. In addition to increasing the efficiency of today's power conversion systems, GaN transistors open up new applications such as RF envelope tracking and wireless power transmission that are much needed to keep pace with the ever-expanding communications industry and battery operated products. These new applications are enabled by the high frequency switching capability combined with the high voltage and high power capabilities of gallium nitride FETs."

42: Cree Technology Breakthrough Enables 50A Silicon Carbide Power Devices

In what the company describes as a breakthrough that redefines performance and energy efficiency in high-power applications, Cree, Inc. announced a new family of 50A Silicon Carbide (SiC) devices, including the industry's first 1700V Z-FET™ SiC MOSFET. These new 50A SiC devices, which also include a 1200V Z-FET SiC MOSFET and three Z-Rec® SiC Schottky diodes, will enable a new generation of power systems with record-setting energy efficiency and lower cost of ownership than with conventional technologies.

The new devices, available in die form, are designed for high-power modules for applications such as solar power inverters, uninterruptible power supply (UPS) equipment and motor drives. Using the Cree SiC 50A devices, power electronics engineers can set new standards for system cost of ownership through reduced size, lower-cost bill of materials (BOM), and improved efficiency.
