On June 24, 2014, Dalian United Holdings, a leading electronic component distributor dedicated to the Asia-Pacific market, announced that its subsidiary will launch an intelligent lighting solution based on Toshiba TB62D901FNG step-down non-isolated LED lighting driver IC. .
The TB62D901FNG is a constant current driver IC suitable for use in buck AC/DC conversion LED lighting applications. The architecture includes an automatic turn-off period adjuster that suppresses variations due to input voltage fluctuations or LED forward bias, providing a stable and uniform LED current for the system. The device allows for linear dimming or PWM dimming, and has a wide range of detection functions, thermal shutdown, over current, over voltage, low voltage latch and current sensing input terminals (ISEN1) open circuit detection.

The United Nations General Group is responding to the market demand for low-power, intelligent lighting, and Toshiba-based products provide a variety of needs for LED smart lighting applications. Such as higher performance non-isolated LED controllers. Schottky diode series products with low on-voltage and high-power LED with high price and high price.
Schottky diode lineup
High-power high-efficiency LED light-emitting diode
The traditional method of producing LED chips is done on a 2 to 4 inch chip with an expensive sapphire substrate. Toshiba and Bridgelux, Inc. have developed a process for fabricating gallium nitride light-emitting diodes on 200 mm silicon chips. Toshiba has also invested the process in its Kaga Toshiba Electronics Corpora, a home in Kaga Toshiba Electronics Corp. A new production line for discrete device manufacturing plants in northern Japan.
The use of Toshiba and Puri's new GaN-on-Si technology to produce LED chips has enabled Toshiba to eliminate the need for sapphire substrates and to produce chips on more cost-competitive silicon substrates.
Low-power and long-life white LED lamps are becoming more widely used in general lighting, television backlighting, and other applications.

USB4 specifies tunneling of:
USB 3.2 ("Enhanced Superspeed") Tunneling
DisplayPort 1.4a -based Tunneling
PCI Express (PCIe)-based Tunneling
Main Benefits of USB 4
The new USB 4 standard has three main benefits over prior versions of USB.
40 Gbps Maximum Speed: By using two-lane cables, devices are able to operate at up to 40 Gbps, the same speed as Thunderbolt 3. The data is transmitted in two sets of four bidirectional lanes.
DisplayPort Alt Mode 2.0: USB 4 supports DisplayPort 2.0 over its alternative mode. DisplayPort 2.0 can support 8K resolution at 60 Hz with HDR10 color. DisplayPort 2.0 can use up to 80 Gbps, which is double the amount available to USB data, because it sends all the data in one direction (to the monitor) and can thus use all eight data lanes at once.
Better Resource Allocation for Video, PCIe: In lieu of alternative mode where the other interface takes over the connection, USB 4 devices can use a process called "protocol tunneling" that sends DisplayPort, PCIe and USB packets at the same time while allocating bandwidth accordingly.
