Power supply provides low ripple in small areas
A fully integrated switching mode power supply that combines high power density, low ripple, with high efficiency and reliability is being intro-duced by Diversified Technologies, (DTI) of Bedford, MA, USA. The DTI High Voltage Switching Mode DC Power Supply features all solid-state construction and offers 1 to 50kW adjustable power at levels from 100 to 240kW with > 0.02% regulation and 1.5 x 10-3 % peak-to-peak ripple.
Current transducers measure 25 to 100A DC, AC or pulsed
Able to be mounted on PCBs or non-intrusive, isolated measurements of DC, AC and pulsed currents from 25 to 100A nominal, LEM has unveiled the LH transducer family. The LH 50-P and LH 100-P are designed for 50 and 100A nominal, respectively, while the LH 25-NP is a multi-range model that can be configured for 8, 12 or 25A, providing the equivalent of three transducers in one device.
Compact gate drivers feature increased creepage distance
Infineon has added a number of wide body package options to its EiceDRIVER Compact galvanically isolated gate driver IC family. The 7.62mm (0.3") 1EDI Compact devices are supplied in a DSO-8 package offering increased creepage distances and improved thermal behaviour.
‘Protect. Control. Sense’ at PCIM 2016
At PCIM Europe 2016 in Nuremberg from 10th to 12th May 2016, Littelfuse will be unveiling families of SiC Schottky diodes and silicon IGBTs in Booth 7-140. An in-booth demonstration will illustrate the capabilities of Monolith’s SiC MOSFET technology with a 5kW buck converter with 675V nominal input and 350V nominal output. The converter switches at high frequencies around 200kHz with an efficiency over 98% that cannot be achieved with sili...
DC/DC converters deliver 3W in a compact SIP4 package
Featuring ultra-high power density and a very compact size, the RI3 series of 3W DC/DC converters have been introduced by RECOM. The modules fit into a compact SIP4 case almost the size of a coffee bean (11.5x10.2x7.6mm), making them suitable for applications where space is limited.
DC/DC regulated power supply conforms to UL, CE & RoHS
Acopian Power Supplies has announced that their Narrow Profile DC/DC Regulated Power Supply Series is certified to UL 60950 (Information Technology Equipment) and UL 508 (Industrial Control Equipment) Safety Standards, conforms to the low voltage directive legal requirements to achieve CE marking, and is RoHS Compliant.
Breakthrough on safer & smarter batteries
For anyone who’s ever panicked when their mobile device chirped, “low battery", the future could be far less stressful, thanks to the advanced battery research of scientists at the Toyota Research Institute of North America (TRINA). A breakthrough involving magnesium batteries may soon open the doors for smaller, longer-lasting batteries for everything from cars to cell phones.
Simple interface makes microstepping easy & accurate
Allegro MicroSystems Europe has introduced a family of complete microstepping motor driver ICs with built-in translators. The A5976, A5977 and A5979 have been designed to operate bipolar stepper motors in full-, half-, quarter-, eight, (A5977) and sixteenth- (A5976/79) step modes. All have the output drive capability of 40V and ±2.8A and include a fixed off-time current regulator that has the ability to operate in slow, fast or mixed-decay...
DC/DC converter features a 38-60VDC input voltage
Semiconductor Circuits introduces the CPE17B50 'Cool Power Technologies' 12V, 16.7A wide input range 8th brick DC/DC converter. This compact part is designed for use in Bus Converter applications and is intended to directly replace larger quarter bricks modules (identical pin out and functionality.) The converter features a 38-60VDC (48VDC nominal) input voltage and has a 12VDC output rated at 200W.
Bespoke high-voltage power modules target laboratory equipment
Bespoke high-voltage power solutions for UK and European customers seeking to develop highly miniaturised scientific equipment, such as mass spectrometers for use in laboratories and medical centres have been introduced by Luso Electronics. Through its partnership with US-based HVM Technology, Luso already distributes standard and customised military grade high-voltage power converters and compact power supplies for night vision applications.
