Power supply meets IEC 4th edition EMC
SL Power Electronics announces its 425W, single output MU425 Series AC/DC power supply. This latest offering addresses the complexity and unique power needs of healthcare systems such as surgical equipment, home healthcare therapeutic devices and imaging equipment as well as other critical medical applications that require clean, reliable power for the highest level of performance.
Power adapters meet US and European energy efficiency standards
Aimed at industrial, networking, peripheral, and test and measurement devices, Phihong has introduced a new range of 120W desktop power adapters that provide energy efficient power solutions. The new adapters feature a universal 3-wire IEC320-C14 input connector, are rated for AC inputs spanning 115-230V AC, and are available in five DC output voltages - 12V, 24V, 48V, 54V, and 56V.
Non-Isolated DC/DC switching regulators
Powersolve's PSR30 and PSR60 series of DC/DC switching regulators are designed for battery or distributed power applications. Available from stock the PSR30/60 series features non-isolated outputs of up to 60W with efficiencies as high as 96%.
Cut output resistance by 50% for simultaneous motor drive
Helping save space, reduce power consumption, lower heat dissipation and minimise vibration and acoustic noise in high-speed motion control designs, a bipolar, 2-channel stepping motor driver has been announced by Toshiba Electronics Europe. The TC78S122FNG is rated for a high voltage of 40V and currents of up to 2.0A. Target applications include surveillance cameras, ATMs, office automation equipment, factory automation and home appliances.
550W ATX power supply features built-in 24V battery charger
TRUMPower introduces the Intel’s Haswell compatible TMPC-550U, which is a medically approved 550W ATX PC power supply equipped with a built-in 24V battery charger. A single 24V or two 12V lead-acid batteries in series can be connected to the TMPC-550U to be used as an interruptible power source, with the backup power being 400W. The battery charger in conjunction with a built-in DC to DC converter ensures that all connected equipment will r...
Method allows the production of high-performance transistors
Working in collaboration with colleagues around the country, University of Wisconsin-Madison engineers have pioneered a unique method that could allow manufacturers to easily and cheaply fabricate high-performance transistors with wireless capabilities on huge rolls of flexible plastic.
The secret to batteries with greatly lengthened lifespans
University of California, Irvine researchers have invented nanowire-based battery material that can be recharged hundreds of thousands of times, moving us closer to a battery that would never require replacement. The breakthrough work could lead to commercial batteries with greatly lengthened lifespans for computers, smartphones, appliances, cars and spacecraft. Scientists have long sought to use nanowires in batteries.
Switching regulator delivers 93% efficiency at 2MHz
The new LT8608 from Linear Technology is a 1.5A, 42V input synchronous step-down switching regulator with synchronous rectification topology that delivers 93% efficiency while switching at 2MHz. This enables designers to avoid critical noise sensitive frequency bands, such as AM radio, while using a very compact solution footprint. Burst Mode operation keeps quiescent current under 2.5µA in no-load standby conditions making it well suited f...
DC/DC converters provide more power output in the same space
Comprised of four models with nominal input voltages of +5 or +12VDC and outputs of +5, +12 or +15VDC, the NXE2 series of 2W SMT DC/DC converters have been announced by Murata Power Solutions. Footprint compatible with similar 1 and 2W devices available and measuring just 12.5x4.36x10.41mm, the NXE2 series provides more power output in the same space.
Switching regulators feature adjustable frequency
Allegro MicroSystems Europe has introduced two adjustable high frequency DC/DC step-down switching regulators with an integrated high-side power MOSFET suitable for power supply requirements of the latest infotainment systems. Allegro’s A8586 provides up to 3.5A output current; while the A8587 has output current of up to 2.0A. Both devices are automotive AEC-Q100 qualified and incorporate current mode control for fast transient response.
