The Power Sources Manufacturers Association (PSMA) has announced publication of The Handbook of Standardized Terminology for the Power Sources Industry–3rd Edition . Revised and expanded, this unique handbook contains hundreds of added terms, especially selected for the power electronics professional. The third edition also contains illustrations and four new appendices, including a listing of EMI specifications, excerpts from international st...

The A3903 from Allegro MicroSystems Europe is a low-voltage bidirectional DC motor driver IC in an ultra-compact package measuring only 2 mm square and 0.55 mm high. The new device has a typical input voltage range of 3 to 5.5 V and produces an output current up to 500 mA. The output uses a full-bridge circuit incorporating source-side linear operation to produce a constant voltage across the motor coil. This regulated output minimises motor volt...

Power Sources Unlimited has introduced the Tracopower TSP Series, of high performance DIN-rail power supplies which are now certified to the IECEx Scheme for explosive atmospheres. Featuring a rugged metal case, complete with shock and vibration proof construction, the TSP Series is designed to provide reliable power even in the most difficult factory conditions.

The C5100 Series is available in 3 standard DC input voltage ranges from 320-800VDC as well as 3-Phase AC input voltages of 3 x 400VAC (320-460) and 3 x 480VAC (400-530). Single outputs are available in 6 standard ranges from 23-200VDC. All outputs are adjustable and fully regulated to 0.2% or better (load) and 0.1% (line).

AnalogicTech has introduced the first in a family of flash LED products capable of driving either two LEDs up to 500mA or a single LED up to 1A. Designed to be used with newer-generation, high-current/high-brightness flash LEDs in mobile phones with video recording, the AAT1270 step-up current regulator delivers the high current levels needed to support flash lighting for higher resolution CCD imagers in a single 3x3mm STDFN package.

Power Integrations today announced a new series of technical design seminars to be held in over 40 locations worldwide. The seminars will offer instruction on how to build power supplies with high energy efficiency, excellent standby power performance and compliance with existing and proposed power supply efficiency regulations worldwide.

Linear Technology has introduced the LTC2917, a single voltage supervisor capable of monitoring a wide 0.5V to 12V input range. The LTC2917 can monitor 27 unique pin-selectable thresholds, ranging from a 1V drained single AA battery up to 12V industrial applications. Competitive solutions require separate supervisors for each of these different voltage thresholds. The LTC2917 VCC supply also includes a 6.2V shunt regulator for monitoring input vo...
