Cosel has used GaN transistors, planar magnetics and a modified fly-back topology to shrink a family of dc-dc power supplies. Called the TE series, the new supplies come in 45W (TECS45F and TEPS45F) and a 65W (TECS65F or TEPS65F) forms. TEPS versions have connections brought out to PCB pins and have a 1 x 2.3inch footprint, while TECS parts (right) ...

Team αCentauri, part-sponsored by Power Integrations, has just completed the 3,022km Bridgestone World Solar Challenge in Australia. It was the 12th and final finisher, ahead of the many teams that failed to finish, and quite a few that failed to start. It wasn’t only cash sponsorship, as a Power Integrations InnoSwitch3 fly-back converter powers low-voltage loads including the steering wheel ...

Intel’s aspiration of bringing up five processes in four years is on track, says CEO Pat Gelsinger. “Our Intel 3 process is tracking to be manufacturing ready by year-end,” said Gelsinger at the Q3 results call, “we are particularly excited by our move into the Angstrom era with Intel 20A and Intel 18A. I have been studying SEM diagrams for ...

Renesas has revealed more on the Arm Cortex-M85 based microcontrollers it announced at Embedded World in May, and started shipping them today. Initial parts are general-purpose and consigned to what Renesas has named the RA8M1 group of the RA8 series. Common specs of RA8M1 parts are: 480MHz Cortex-M85 with Helium and TrustZone, 1 or 2Mbyte programme flash, 12kbyte data flash, ...

Imec has designed a low-power, miniature chip for large-scale recordings that claims to be 16 times smaller than the state of the art. The  miniaturisation (total area per channel of 0.005mm2) was achieved by applying smart design solutions on the one hand and harnessing the advantages of a smaller technology node on the other hand. It uses a direct digitisation ...

EPC has come up with a 3-phase BLDC motor drive inverter reference design which operates from an input supply voltage range of 14 V to 60 V and delivers up to 60A output current. This voltage range and power level makes the EPC9194 suitable for a variety of 3-Phase BLDC motor drives including eBikes, eScooters, drones, robots, DC servo motors. The ...

With Q3 only showing a 0.1% y-o-y decrease to 302.8 million units, the smartphone market is set for a rise, says IDC’s Worldwide Quarterly Mobile Phone Tracker. “We are seeing a strong ramp up of shipments in emerging markets by vendors like Xiaomi and Transsion,” says IDC’s  Nabila Popal, “while this is a good sign of approaching recovery, vendors must ...

Mira Aerospace has announced its “ApusDuo” solar aircraft has successfully conducted a 5G connectivity test, delivering comms from a fixed-wing HAPS (high altitude pseudo satellite) autonomous aircraft in the stratosphere. The demonstration (pictured) was conducted in Rwandan airspace and delivered 5G connectivity for approximately 73 minutes in the stratosphere, says the company, during which it reached a maximum altitude of ...

SIR – I was interested to see on the back page of your issue of September 14, reference to American work on communications satellites, employing stationary orbit. I was disappointed, however, not to see any reference to our work in England on closer non-stationary orbit for communication purposes. So, 63 years ago, started a letter to the editor in Electronics ...

EEMBC, the Embedded Microprocessor Benchmark Consortium, has joined the Standard Performance Evaluation Corporation (SPEC) and has become ‘SPEC Embedded Group’ (SPEC EG). Both SPEC and EEMBC are non-profit organisations. Started before the millennium by EDN magazine (hence the extra initial ‘E’), and later spun out, EEMBC has developed respected industry benchmarks for measuring the processing performance and energy efficiency of ...
