IEEE 802.3BT PD CONTROLLER PAVES PATH TO HIGHER POWER FOR POE++


requiring up to 71W of delivered power. The next Power over Ethernet (PoE) standard – IEEE 802.3bt – enables manufacturers to go beyond the 25.5W allocated by the 2009 IEEE 802.3at standard. The new standard, also known as


L


inear Technology Corporation has introduced its LT4295 IEEE


802.3bt powered device (PD) interface controller for applications


PoE++ or 4PPoE, increases the power budget to enable new applications and features, while supporting 10 Gigabit Ethernet (10GBASE-T) and maintaining backward compatibility with older


IEEE equipment. The LT4295 is IEEE 802.3bt (Draft 2.0) compliant and supports newly introduced features, including all additional PD classes (5, 6, 7 and 8), additional PD types (Type 3 and Type 4), and 5-event classification. This device is a single-signature


802.3bt PD controller that integrates an isolated switching regulator controller, capable of synchronous operation in both high efficiency forward and no-opto flyback


topologies with auxiliary power support. This high level of integration simplifies front end PD designs by reducing component count and board space, allowing the LT4295 to efficiently deliver power to PD loads using just one IC. Unlike traditional PD controllers that integrate the power MOSFET, this device controls an external MOSFET to significantly reduce overall PD heat dissipation and maximise power efficiency. www.linear.com/product/LT4295

MODULAR POWER SUPPLY SERIES HAS LOW ACOUSTIC NOISE, IDEAL FOR MEDICAL


A new series of AC-DC power supplies has been released by TDK Corporation. The company’s QM series are 1200W to 1500W rated modular power supplies with full MoPPs isolation, offering a remarkably low acoustic noise. Having both medical and industrial


safety certifications, these devices are suitable for a wide range of applications, including BF rated medical equipment, test and measurement, broadcast, communications and renewable energy. The company advises it offers an


online configurator to help select the right product, giving an optimised


module choice of signals, leakage current and standby voltages. Once the desired output voltages and currents have been entered, the configurator will automatically produce a unique 8-digit code for easy order placement. With a wide range 90-264Vac, 47-


440Hz input the QM can deliver 1200W, and 1500W with a 150-264Vac input. Up to 16 outputs can be provided, with voltages ranging from 2.8V to 52.8V, with additional higher voltages later. Module power ratings start with a low


power 35W, with single or dual outputs, all the way to a powerful 1200W single


output. The units will operate in ambient temperatures of -20 to 70°C, derating output power and output current by 2.5% per °C above 50°C. Overall case dimensions are a compact 176 x 63.3 x 270mm (W x H x D), and the weight is between 2.6 and 3.1kg, depending on the module configuration. These devices are also covered by a seven-year warranty. An optional standby/signal module is


available with a choice of one or two standby voltages (5V and 12V at up to 2A). It also contains unit inhibit or unit enable, plus an AC Good signal. www.tdk-lambda.com


A new power analyser has been launched by Yokogawa Europe. The WT1800E was developed to be flexible enough to provide accurate and reliable power measurements for applications as demanding as the manufacture of energy efficient devices and appliances, Plug-in hybrid/electric vehicles, lighting, aircraft and for renewable energy technologies. It is the perfect device for comparisons of the input and output of for example; motors, inverters, actuators, energy recovery systems and generators.

Renesas Electronics Corporation and Intersil Corporation have signed an agreement for Renesas to acquire Intersil. The companies advise by combining Renesas’ microcontroller (MCU) and system-on-chip (SoC) products and technologies and Intersil’s power management and precision analogue capability, Renesas will be well positioned to address some of the most exciting opportunities in key areas such as automotive, industrial, cloud computing, healthcare, and IoT. The acquisition is also expected to


grow Renesas’ served product lines, particularly for analogue devices, where the market is expected to increase by approximately US$3.9 billion by 2020. “Renesas is accelerating its focus of


resources in automotive, industrial, infrastructure, and the rapidly growing IoT segments to grow its global business and maintain its market position. Intersil’s current portfolio of analogue and power devices as well as its strength in the automotive, industrial, and broad-based segments


complement many of Renesas’ initiatives in these areas,” said Bunsei Kure, Representative Director, President and CEO of Renesas Electronics Corporation. “We believe that this compelling and


complementary combination will bring significant synergies and cross selling opportunities as well as system solution proposition, which will pave the way for Renesas to strengthen its position in the global semiconductor market while delivering value to its customers with a unique product offering.” “Intersil has been part of the


industry’s evolution for many decades, carving out key niches and developing core technology that provides tangible benefits over competing solutions,” said Necip Sayiner, President, CEO and Director of Intersil Corporation. “As we’ve embarked on the most


recent transformation over the last three years, we have honed the company’s core capabilities and focused them on areas where we are well positioned to solve customer system challenges. www.renesas.com


Microchip has released its new Explorer 16/32 Development Board for designing with 16-bit and 32-bit PIC microcontrollers. This new board comes with an integrated programmer/ debugger and several new features for embedded systems design. It offers a platform for evaluating the 16-bit PIC24, dsPIC33 and 32-bit PIC32 families of devices through Processor Plug-In-Modules (PIMs) for easy device swapping.

Toshiba Electronics Europe and EBV Elektronik are celebrating 20 years of working together. Collaboration between the two companies has grown from strength to strength and now sees EBV as one of Toshiba’s most important world-wide distribution partners. The association, which began on the 1st September 1996, originally covered selected countries in central Europe. However, after five months was expanded to cover the whole of Europe. This partnership quickly saw yearly sales figures surpass $20 million, with a particular focus on couplers and MCU/Echelon interception systems. Since 2013, it has been recognised that a closer working relationship between distributor and manufacturer is vital in order to meet the exacting demands of today’s developers and designers.
