Yes, APEC 2020 organizers are promising paper presentations online but it looks like one fast and furious Silicon-Valley-based supplier of power electronics just took up the virtual-exhibit show banner with today’s launch of the Power Integrations Virtual Booth — APEC 2020. The premier global event in applied power electronics that was to take place this […]
Power control ICs handle 90-W PoE connections
Silicon Labs has introduced a comprehensive Power over Ethernet (PoE) portfolio that reduces the cost and complexity of adding 90 W PoE to power sourcing equipment (PSE) and powered devices (PD). The new 90 W PoE portfolio complies with the IEEE 802.3bt standard, which more than doubles standard PoE power and expands the capabilities of wireless access […]
Battery-management IC extends driving range, reliability, and safety of EVs
STMicroelectronics has revealed new battery-management technology that increases reliability, safety, driving range, and cost-effectiveness of electric vehicles (EVs). EVs are predicted to reach cost parity with conventional combustion-engine vehicles before the end of this decade and overtake in sales volume by 2038. ST, leveraging its technical capabilities to help carmakers achieve these goals, has announced an […]
Thermal propagation triggering and mitigation in medium- and large-format battery modules
by Iris Su, Project Engineer II, Inventus Power A recent change in Li-ion battery pack safety is the shift from a focus on just prevention to one that emphasizes prevention and mitigation. Battery pack designers who were once focused on preventing thermal runaway (TR) are now taking increasing measures on preventing single cell failures within […]
Power management IC optimized for i.MX 8M Nano application processors
Rohm Semiconductor announced the availability of a highly integrated and efficient power management IC (PMIC), BD71850MWV, optimized for NXP Semiconductors’ i.MX 8M Nano family of application processors, which features exceptional computing, and audio performance. It is the latest addition to ROHM’s growing portfolio of PMICs designed for NXP’s i.MX application processors. With the BD71837AMWV for […]
Electric locomotives and catenary power systems – Part 3: power delivery
The high-speed all-electric railroad locomotive uses a catenary-wire system and pantograph power-transfer arrangement, which appears to violate good engineering practice and should not work. Still, it does, transferring hundreds of amps via a contact point moving at over 100 miles/hour. Part 2 of this article looked at power issues and numbers related to the electric […]
PMICs optimized to handle multiple automotive HD camera modules
Renesas introduced its latest solution to streamline power supply design for automotive, expanding its support for automotive surround view cameras into the design of HD satellite cameras. The highly integrated ISL78083 PMIC reduces development cycles, bill of materials cost, and supply chain risks to simplify power supply design for use in multiple HD camera modules. The […]
Super-efficient dc-dc converters target fast-charging mobile device apps
Halo Microelectronics announced two new products that utilize switched capacitor architecture to deliver 98% efficiency DC-DC conversion, which outperforms traditional DC-DC converters by up to 10% efficiency. This higher efficiency significantly reduces the thermal dissipation in mobile devices such as smartphones, thus enabling more power to be delivered to the battery and resulting in a […]
Automotive display PMIC takes the place of four discrete ICs
Designers of automotive electronic systems can now increase the number of displays per vehicle while reducing design complexity by using the MAX16923 4-output display power IC with watchdog timer from Maxim Integrated Products, Inc. By replacing four or five discrete ICs with a single power management solution, the MAX16923 significantly shrinks solution size and makes it […]
