With USB Power Delivery in mind, EPC has designed a 180W GaN dc-dc converter evaluation board. Its two-phase power section occupies only 24 x 24mm, using both sides of the board and ignoring input and output bulk capacitors. Called EPC91109 and intended to implement USB-PD 3.1, it delivers 12, 16 or 20V from an input range of 20 to 36V. ...

Aaronia will reveal USB and portable real-time spectrum analysers at the IMS Microwave Symposium in San Francisco next week. Spectran V6 Mobile is the portable analyser (photo right), with a real-time bandwidth of 490MHz. “This means that even the 320MHz wide channels of the new IEEE 802.11ax standard can be fully recorded,” according to the company. “The tablet, which is ...

Toshiba has created a pair of 32Gbit/s multiplexer/demultiplexer switches, intended to switch two differential pair signal paths, or four single-ended signal paths, between a single port on one side and two ports on the other. The devices are aimed at high speed serial busses including PCIe 5.0/4.0, CXL 2.0/1.0,  USB4 Version 2.0, Gen3/Gen2, USB 3.2 Gen 2/Gen 1,  Thunderbolt 4, ...

Bulgin is extending its range of circular data connectors for rugged conditions, including Ethernet, USB and HDMI (pictured) interconnects. Aimed at harsh environments – such as industrial automation and wind and solar energy applications – the connectors have a rating of up to IP69K when mated, and are available in multiple cable lengths and mounting options. Specifically, there will be ...

Transistor maker Cambridge GaN Devices has signed a memorandum of understanding with Taiwan’s Industrial Technology Research Institute to develop USB-PD adaptors as well as to share international market information, visit to potential customers and promote the PSUs. The agreement covers 140 – 240W, >30W/in3, ac-dc power adapters for e-mobility, power tools, notebooks and phones (prototype GaN-based USB PD adapter right) ...

A French-Taiwanese collaboration has produced a primary-side IC for 65W ac-dc USB PD adapters. The companies are GaN specialist Wise-integration and mixed-signal IC maker Leadtrend Technology. Together that have created LD966L, a 650V system-in-package multi-mode PWM fly-back converter with Leadtrend’s silicon controller die and an enhancement-mode GaN transistor die from Wise. It comes in an 8x8mm QFN package and its ...

Toshiba has launched its first 30V n-channel common-drain dual mosfet, for controlling bi-directional power flow in USB-connected devices. The USB Power Delivery standard supports power levels from 5V 3A to 48V 5A, and allows swapping of the power supply and receiving side, requiring devices with USB charging to support bi-directional power. In developing a 30V common drain mosfet, called SSM10N961L, ...

Microchip has created a set of dual-channel single-lane USB 3.2 Gen1 SuperSpeed reclocker redriver ICs for automotive and industrial cables up to 15m long. “Adding electronic components to applications across automotive, industrial and consumer industries has spurred the need for far-reaching USB cabling products,” according to the company. EQCO510 is the automotive version, qualified to AEC-Q100 Grade 2 and operates ...

The USB Implementers Forum has certified a USB-C source-sink IC pair and the associated reference designs for 140W (28V 5A) USB PD EPR (USB power delivery extended power range). “The new ICs extend the range of a universal charger to 140W,” according to STMicroelectronics, which has created the ICs and the designs. “Now, a single ac-dc adaptor can charge equipment ...

Lemo has developed USB 3.1 version of its push-pull latching connectors for use up to 10Gbit/s. They are available in the company’s B, K and T series (see table) for demanding indoor and outdoor environments, for applications in defence, industrial automation, data communication, aerospace, test and measurements. B Series miniature K Series robust T Series miniature Ingress IP50 IP66 – ...
