AC/DC power modules are fully waterproof
A series of fully waterproof AC/DC power modules have been introduced by MTM Power. The PM-IP67A series is comprised of 50, 75, 100 and 200W devices.
ADCs & DVGA combine for high performance & low power
Texas Instruments has announced ADS54J60, the industry’s first 16-bit 1-GS/s ADC, achieving over 70dBFS SNR at 1GS/s, as well as its high density four-channel 14-bit 500MSP/s ADC, the ADS54J54. To optimise the signal chain, TI’s 4.5GHz LMH6401 fully differential DVGA offers the widest bandwidth with DC coupling and allows signal acquisition of low and high frequencies without the limitation of baluns used in AC-coupled syste...
Desk-top mini DC UPS provides a 12VDC output
A desk-top mini UPS, from Powersolve, provides a 12VDC output in the event of an AC mains failure. The PUPS22-12 works from a 12VDC input using an AC-DC adapter such as Powersolve’s ESA36-12 and simply plugs in between the adaptor and the load. According to Powersolve, the UPS is suitable for powering networking devices such as routers and other low power devices.
Compact dual LDO regulator offers high accuracy
A dual 300mA LDO regulator that offers high 1% output accuracy and a low quiescent current of 50μA is currently being offered from Diodes Incorporated. The AP7344 features a small package to suit battery-powered consumer products such as cameras, smart phones and tablets.
Power module combines an IEGT & fast recovery diode
Suitable for use in rail traction, industrial motor control, renewable energy systems and electricity transmission and distribution applications, the MG1200GXH1US61 power module has been released by Toshiba Electronics Europe. The 4500V, 1200A device integrates an N-channel IEGT and a fast recovery diode into a standard package with a footprint of just 140x190mm.
Electrical isolation in medical device setups
The increased complexity of medical device setups is causing concern in the medical industry. As more and more healthcare professionals use a variety of electrical equipment as part of their diagnosis and measurement regime, there is a knock-on effect on the stability of the mains power supply. Here, Steve Hughes, Managing Director at REO UK, explains the importance of electrical isolation and good product design.
DC/DC converter offers high efficiency & thermal performance
Delivering up to 50A with a single fully regulated 12V output, a series of 600W quarter-brick isolated DC/DC converters has been unveiled by Artesyn Embedded Technologies. The ADQ600 series has an input voltage range of 40 to 60V and is primarily designed for use with standard 48V supplies in computing and server applications, as well as regulated 48V supplies in telecomms equipment.
DC/DC converters and LED drivers debut at PCIM
Tech Power Electronics will be showing its low power DC/DC converters at PCIM Europe 2015 (Hall 7 - 326).
Adaptors have a no load power consumption of less than 0.15W
A series of 60W AC/DC adaptors, which are IP67 rated, has been introduced by Mean Well. The OWA-60E devices feature a low no load power consumption of less than 0.15W and an efficiency of up to 91%, meeting the latest international energy related regulations.
RF power transistor delivers 20dB typical gain
The MAGX-000912-650L0x is a gold-metalised, matched gallium nitride on silicon carbide RF power transistor from MACOM, that is optimised for civilian and military pulsed avionics amplifier applications in the 960 MHz to 1215 MHz range, such as Mode-S, TCAS, JTIDS, DME and TACAN.
