Analog Devices Bidirectional Buck-Boost Controller
Analog Devices has announced the LT8708/-1, a 98 percent efficient bidirectional buck-boost switching regulator controller that operates between two batteries that have the same voltage, and which are is ideal for redundancy in self-driving cars.
The LT8708/-1 operates from an input voltage that can be above, below or equal to the output voltage, making it suitable for two 12V, 24V or 48V batteries commonly found in electric and hybrid vehicles. It operates between two batteries and prevents system shutdown should one of the batteries fail.

Cypress Wireless Audio Stereo Synchronization
Cypress Semiconductor has launched a Bluetooth audio system for wireless earbuds and hearables. Based on the Wireless Audio Stereo Synchronization (WASS) application and the CYW20721 Bluetooth and Bluetooth Low Energy (BLE) Audio microcontroller (MCU), the system provides connections for differentiated performance in wireless earbuds.
The MCU features a link budget that is 6dB greater than before, resulting in up to twice the range. The extended range provides increased cross-body performance, giving users uninterrupted audio on their earbuds when carrying their smart devices in their back pockets or wearing them on their wrists.

Renesas Signal Processor
Renesas has introduced an integrated open image signal processor (ISP) platform to speed the development of automotive smart camera applications that are based on the company’s R-Car V3M and R-Car V3H System-on-Chips (SoCs).
Integrating the ISP on the R-Car V3x SoCs and utilizing MM Solutions’ Automotive Camera Development Kit (AutoCDK), the open ISP solution on R-Car SoCs enables automotive Tier 1s to simplify the sensor calibration and tuning process for camera applications, including front camera and surround view.

TI USB Power Delivery Controllers
Texas Instruments (TI) has launched two USB Type-C and USB Power Delivery (PD) controllers that have integrated power paths to simplify designs, minimize solution size, and speed time to market. The TPS65987D and TPS65988 can also reduce design complexity and overall costs.
The TPS65987D, a single-port device designed to source 100W of power, includes independent 20-V, 5-A source and sink load switches. Low RDS(on) (25 mΩ) and reverse current protection in the TPS65987D provide a way of managing a port's charging needs.

VTT 3D Printing with Nanodiamonds
VTT and Carbodeon have developed a plastic filament called uDiamond that is suitable for consumer and industrial use, providing faster 3D printing and improvements in the mechanical durability of printouts.
A nanodiamond or a diamond nanoparticle, which is produced by material explosions, is one of the best thermally conductive and hardest materials known. The performance of the 3D printing filament is based on the nanodiamond particles it contains and their ability to shape the structure and properties of the material. The material’s spherical nanodiamonds work like a lubricant and do not increase the clogging of the printer nozzle.
