Helping to migrate from X-ray to direct radiography
The migration away from traditional X-ray imaging towards Direct Radiography (DR) is gaining momentum, now the initial ownership costs are decreasing and its benefits become more apparent. By Afshin Odabaee, Product Marketing Manager, µModule Power Products, Linear Technology.
Controller targets portable device chargers
Designed for portable electronic device chargers, the APR343 synchronous rectification controller has been introduced by Diodes Incorporated. To support a primary side control system, the device integrates a secondary side MOSFET driver with an output voltage detection function.
Open frame power supplies meet international standards
A range of open-frame power supplies ideal for use in systems such as industrial controls, computing, test gear, network equipment and medical applications are now on sale at Dengrove Electronic Components. The latest RECOM RAC48/OF and RAC60/OF 48W and 60W power supplies are compliant with worldwide safety standards as well as the European ErP Directive.
650V SiC Schottky diodes suit PFC & power conversion
Addressing demand for components with a nominal voltage rating slightly higher than 600V, Cree has expanded its SiC Schottky diode portfolio with the addition of four 650V diodes. The Cree Z-Rec diodes, automotive qualified to AEC-Q101, enable high efficiency power systems with improved reliability, simplicity, and total cost.
LED power supply range extended downwards with 60W model
Mean Well has announced that its HBG-100/160/240 series of circular LED power supplies has been widely applied to various kinds of the bay lighting applications since it was released to the market. In order to meet demand for lower wattage power supplies, Mean Well has extended output power down to 60W, and is pleased to unveil the HBG-60 series.
Doherty power amp enables control processing flexibility
To address the needs of small cell designers, Cree has introduced the CDPA35045 asymmetric Doherty Power Amplifier (PA) reference design for the 3.5-3.7GHz band. This band is an additional spectrum space intended to complement small cell technology by providing increased wireless system capacity for both licensed wireless carrier services and unlicensed public use, such as WiFi.
EDLC cell balancing IC reduces mounting area by 38%
Contributing to increased miniaturisation, greater stability and longer life for EDLCs, the BD14000EFV-C cell balancing IC has been released by ROHM. The device integrates over 20 discrete components required for EDLC cell balancing on a single chip, reducing mounting area by 38%. This also eliminates component variations, making it easy to configure EDLC systems.
500W power supply features a typical efficiency of 92%
A 500W convection cooled AC/DC power supply, which features a typical efficiency of 92%, has been released by Excelsys Technologies. Operating from 90-264VAC, the XS500 delivers 500W output power without the need for forced air cooling. The device is, therefore, suitable for use in a wide range of acoustic and vibration sensitive applications as well as hi-rel applications where fans are not permitted.
Battery manufacturers face the power budget quandary
Neil Oliver, Technical Manager, Accutronics, explains the power budget quandary medical device designers face, and how battery manufacturers can help.
Load switch provides 36mΩ in 0.76x0.76mm package
Offering a 2A, 1.1-3.6V power rail with controlled turn-on and -off profiles, the SC724, SC725, SC728 and SC729 load switches have been introduced by Semtech. The SC72X family is suitable for portable applications, including wearable electronics, portable video cameras, smartphones and tablets, as well as non-portable applications such as HDTVs, set-top boxes and networking devices.
