Resistors enable design of portable medical electronics
Electronics equipment for medical applications has escaped the confines of medical facilities and entered the outside world. It’s not just the location of medical electronics that has changed, though – they are no longer the sole preserve of medical professionals. These changes have been enabled by modern design techniques. Today’s medical electronics devices are smaller, lighter and designed to be easy to operate. By Phil...
Fast recovery diode products offer high voltage capability
Specialist in power semiconductors and IC technologies for energy efficient products used in power conversion and motor control applications, IXYS, has announced the introduction of the D3Pak-HV package (TO-268HV). This package offers high voltage capability due to the 1,200V rating designed in the creepage distance. The products introduced in the TO-268HV packages are Fast Recovery Epitaxial Diode (FRED) and the faster version High Performance F...
Compact single output 300W power supplies
A series of compact, single output AC-DC converters designed to provide up to 300W across a wide operating temperature range of -30⁰ to +85⁰C has just been announced by Powersolve. The seven model PSY300 series power supplies are open PCB units with a 3 x 5in footprint. They operate from a wide 90 to 264VAC input range with active PFC.
Industrial grade DC/DC converters have 4:1 input range
The introduction of the GQA120 series of industrial grade DC/DC converters has been announced by TDK Corporation. Rated at 120W output power, the units are available in four robust quarter‑brick package styles designed for use in a wide variety of applications and environments. These include automated guided vehicles, portable electronics, ruggedised communication equipment, track-side rail and marine navigation systems.
Cool designs for miniaturised high-power applications
Some major concerns for modern electronic applications include miniaturisation and increasing power densities. The lifetime of electronic applications can be dramatically reduced by the increase of the working temperatures by just a few degrees. Further, the insulation of the whole printed circuit board (PCB) from the environment in order to provide efficient protection against humidity and dust for certain applications turns heat dissipation an ...
Power-on-Package enables higher performance for AI processors
It has been announced that Vicor has introduced the Power-on-Package modular current multipliers for high performance, high current, CPU/GPU/ASIC (‘XPU’) processors. By freeing up XPU socket pins and eliminating losses associated with delivery of current from the motherboard to the XPU, Vicor’s Power-on-Package solution enables higher current delivery for maximum XPU performance.
MPD release its new and improved Battery Holders Catalogue
The release of the new and improved Battery Holders catalogue has been announced by Memory Protection Devices, Inc. (MPD). It has been completely redesigned from the bottom up, and now users can quickly find the right battery holders for their projects.
Streamlining to simplify
Designers have a choice of power management ICs and power sequencers to simplify powering-up voltage rails for a system on a chip (SoC) or embedded computing subsystem in the correct sequence. By Mark Patrick, Mouser Electronics
