pulse Wireless charging extended to 40W power levels Semtech has demonstrated ultra-high power, 40W, wireless charging technology at the Consumer Electronics Show, CES 2017. Its LinkCharge 40 Series is a backwards-compatible and efficient wireless charging solution that supports Qi standards in a small form factor. “The addition of this 40-Watt, highly differentiated, ultra-high power wireless charging capability to Semtech’s LinkCharge platform makes our robust and scalable wireless charging technology available for products of all sizes and power requirements,” said Ruwanga Dassanayake, Product Line Manager for Semtech’s Power and High-Reliability Products Group. “One of the unique features that sets LinkCharge 40 apart is that its transmitter is backwards compatible, supporting Qi-enabled phones while maintaining small form factor at both ends of the solution.” The high power system architecture of the LinkCharge 40 uses a flexible firmware-based approach and proprietary communication protocol between the transmitter and receiver at 40W and uses the WPC (Wireless Power Consortium) or Qi standard protocol at lower power. Features of the LinkCharge 40 include; high DC-DC efficiency at 85%; 19Vout / 2A at the receiver; capable of supporting multiple coil configurations; and it supports dynamic loads. Intel packages CPUs, FPGAs as GO to target automated driving systems Intel has created the Intel GO branding for automated driving products, including the Intel GO In-Vehicle Development Platform for Automated Driving with Intel formerly Altera FPGAs sitting alongside either an Intel Atom or Intel Xeon processor. Automotive system supplier Denso has been a collaborator in assembling the package of CPUs, FPGAs and software. GO is intended to be a scalable, car-to-cloud system as a step towards a ‘driverless future’ (pictured; development system). Information available at time of writing implies a system configuration that continues to employ discrete Intel CPU chips alongside former Altera FPGAs. The latter now include an Arria 10 chip available as a automotive-specification part. Intel says this will be the highest performance processing automotive FPGA, offering one speed grade performance advantage over competing devices. There seems, for the present at least, no intention to integrate these elements on a single die. Specifically, the new automotivegrade Arria 10GX mid-range FPGA Complete article, here for autonomous driving is up to 40% lower power than previous generation FPGAs and features hard floating-point digital signal processing blocks. The Arria 10 automotive-grade FPGA offers more than 320 Gbps of DDR4 bandwidth and more than 200 Gbps of transceiver bandwidth. It also supports 12G serial protocols, 1.5K variable-precision DSP 6 EDN Europe January 2017 www.edn-europe.com
