Conrad Business Supplies has extended its range of power supplies and supporting accessories, with the addition of more than 650 products from Delta Electronics. The company’s product range is said to offer high efficiency performance in applications requiring a wide input voltage range.

Delta Electronics provides high performance off the shelf power modules, including isolated and non-isolated DC/DC modules, AC/DC power modules and ATCA input modules. Applications cover most mission critical solutions for telecom, networking, datacenter, industrial, healthcare, transportation and LED displays for digital signage markets.

Shawn Silberhorn, Conrad’s supplier business development manager, category business supplies, commented: “We are excited to begin stocking this extensive range of new power supplies. These products will appeal to many of our existing customers who have requirements for dependable, cost-effective and energy efficient power supply solutions.”

Said to be the first 80A fully encapsulated digital DC/DC PMBus power module that provides point of load (POL) conversions for FPGAs, DSPs, ASICs, processors and memory, the ISL8273M is a complete step down regulated power supply that operates from 5V or 12V power rails.

Multi-phase current sharing of up to four ISL8273M power modules enables power supply designers to create a 320A solution with output voltages as low as 0.6V.

Housed in a module measuring 18 x 23mm, the device is said to have delivers the highest power density and performance of similar parts, whilst delivering an output current twice that of competitors.

“With advanced FPGAs and processors occupying more of the PCB real estate and requiring higher input current levels at lower input voltages, the demands on POL power converters are being pushed to the limit,” said Mark Downing, senior vice president of Intersil’s infrastructure and industrial power products. “The 80A ISL8273M gives our customers the power density they need, along with excellent thermal and electrical performance, on the fly power supply optimisation and real time system monitoring and control.”

According to the company, its patented ChargeMode control architecture enables a peak efficiency of 94% and better than 90% efficiency on most conversions. It also provides a single clock cycle fast transient response to output current load steps.

A new series of ARM Cortex-A5 based microprocessors has been launched by Atmel, which says the devices deliver the lowest power consumption of all MPUs in its class. Called the SAMA5D2 series, the parts are said to consume less than 200µA in retention mode with context preserved and to wake up in 30µs. 

Called the SAMA5D2 series, the parts are said to consume less than 200µA in retention mode with context preserved and to wake up in 30µs.

Also featuring an ARM NEON engine, the SAMA5D2 series delivers runs at up to 500MHz. Its memory system includes a configurable 16 or 32bit DDR interface controller, along with a 16bit external bus interface and a QSPI flash interface. There is 128kbyte of SRAM on board, plus a 128kbyte L2 cache which can be configured as an SRAM extension.

Describing the news family as ‘a great migration path’ for designers using ARM926 based MPUs, benefits include a smaller footprint and Atmel’s SleepWalking technology.

“We are excited to launch the SAMA5D2 series for designers requiring a general entry level MPU,” said Jacko Wilbrink, Atmel’s senior director of MPUs. “Designers for industrial IoT, wearables and POS applications are demanding more performance, lower power, smaller form factors and additional security for their next-generation applications. The SAMA5D2 is well positioned for these demanding requirements, delivering the world’s lowest power MPU, along with low system cost and PCI level security.”

CRFS is launching the latest additions to its RFeye node family at DSEI 2015. The RFeye family has been designed for continuous remote monitoring of the spectrum, providing real time information on spectrum use, as well as the ability to map, display and analyse high volumes of data. The devices support direction finding and radio geolocation techniques in regulatory, security and military applications.

The latest models – RFeye Node 50-8 and 100-18 – are said to offer faster sweep speeds, improved sensitivity, bandwidths up to 100MHz and a frequency range of 8GHz or 18GHz.

Alistair Massarella, CEO, said: “Our COTS solutions deliver exceptional RF performance and our software provides the flexibility to address expanded operational needs for more effective use of spectrum while addressing new threats with increased speed and agility.”
