Resonance helps boost power efficiency
Switched-mode power supply (SMPS) topologies have led to advances in efficiency, thanks to continual tweaks and optimisations to circuit design, says Martin Brabham, Stadium Stontronics
100V monolithic flyback regulator simplifies isolated DC/DC design
Linear Technology Corporation announces the LT8303, a monolithic flyback regulator in a TSOT-23 package that significantly simplifies the design of isolated DC/DC converters. By sampling the isolated output voltage directly from the primary-side flyback waveform, the part requires no opto-isolator, LT1431 or third winding for regulation.
Isolated power supply control ICs combine power savings & reliability
ROHM has announced isolated flyback-type DC/DC converter control ICs for Auxiliary Supply in High Power Industrial equipment such as FA/solar inverters and power storage systems. Following the BD7F100, the company now expands the series with the BD7F200, covering all applications with a power requirement from 1 to 10W, and including two different packaging options. In addition, ROHM introduces a BD7F100 evaluation kit that facilitates the design ...
Producing catalytically active gold nanoparticles
An ultra-high-vacuum chamber with temperatures approaching absolute zero—the coldest anything can get—may be the last place you would expect to find gold. But a group of researchers from Stony Brook University (SBU) in collaboration with scientists at the Air Force Research Lab (AFRL) and the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have just demonstrated that such a desolate place is ideal for producing cataly...
Isolated DC/DC converters are in encapsulated package
Three isolated DC/DC converters have been added to the range available from CUI. The PDQ10‑D, PDQ15‑D and PDQ30‑D have outputs of 10, 15 and 30W respectively.
DC/DC converters provide 9W from a SIP-8 package
Powersolve has just introduced what its says is the world’s first SIP-8 packaged DC/DC converter series to provide an isolated and regulated output voltage with up to 9W of output power.Models in the Tracopower TMR9 series are available with 2:1 (TMR 9) or 4:1 (TMR 9WI) input ranges and cover nominal inputs of 12, 24 and 48VDC. Single and dual output voltages of 3.3 to 24VDC are available within the range.
NTC thermistors withstand up to 900J of input energy
A series of inrush current limiting NTC thermistors designed to withstand high input energy from 500 to 900J and steady-state currents from 10 to 50A has been announced by Ametherm. Offering a rugged design, MS35 series devices are optimised for high-power applications, including solar inverters, battery chargers, and DC/DC converters.
DC/DC power module features enhanced isolation & wide input range
PEWATRON has launched a DC/DC power supply module with enhanced 6000VDC isolation. The series boasts an output of 6W and an extremely wide input voltage range of 9–36VDC and 18–75VDC. Comprehensive voltage protection features guarantee outstanding reliability, making it ideal for use in the medical sector. These include input under-voltage protection, output over-voltage and short circuit protection, as well as overload protection.

The conference with its adjacent running trade exhibition is the most important communication platform for power electronics and its applications in Asia in this coming year.The latest date for abstract submissions is 16th November 2016, with PCIM Asia taking place from 27th–29th June 2017 in Shanghai.
The world’s smallest insulated & controlled 9W DC/DC converter
Pewatron AG is launching the world’s smallest insulated and controlled DC/DC converter in the 9W class – the PDL09 range from P-DUKE Power Mate Technology.The PDL09 converter is housed in a small, flat SIP-8 miniature package, measuring just 21.8 x 9.1 x 11.2 mm. But with a power density of up to 66W per cubic inch, it sets a record level in the market, exceeding the levels of the similarly sized PDL06 and standard commercial models b...
