The LT8705 operates over a 2.8V to 80V input voltage range and produces a fixed 1.3V to 80V output, using a single inductor with 4-switch synchronous rectification. Output power up to 250W can be delivered with a single device. Higher power can be achieved when multiple circuits are paralleled. The LT8705 has four feedback loops to regulate the input current/voltage,
The team is led by Alexander Balandin, University of California Presidential Chair in Electrical and Computer Engineering and founding chair of the materials science and engineering program at UC Riverside’s Bourns College of Engineering. Other members of the team are Roger Lake, a UC Riverside professor, Alexander Khitun, a UC Riverside research professor, and Tina Salguero, an assistant professor at
Mining the moon to meet our energy needs may sound like the plot from a sci-fi movie, but China is considering doing exactly that. Helium 3 is an extremely valuable isotope that could be used in clean fusion plants to generate energy – and it’s available in vast quantities on the moon. Some scientists say that the moon is so
Texas Instruments today introduced the industry’s smallest bidirectional 18-V, 5-A protection switches with high power efficiency. These tiny devices reduce solution size and extend battery life in portable and adapter-powered devices, and enterprise and client solid state drives. Industry’s smallest 18-V eFuse power protection system efficiently defends systems Enterprise SSDs are reading and writing more data than ever before, which
The LTC3124 from Linear Technology Corporation is a dual-phase, 3MHz, current-mode, synchronous boost DC/DC converter with output disconnect and inrush current limiting. Dual-phase operation significantly reduces peak inductor and capacitor ripple currents, minimizing component size while delivering lower output ripple versus an equivalent single-phase device. Its internal 2.5 A per phase capable switches together deliver 5 A of switch current.
Infineon Technologies AG expands the comprehensive SiC portfolio introducing the 5th generation1200V thinQ!™ SiC Schottky diodes. The new 1200V SiC diodes feature ultra-low forward voltage even at operating temperatures, more than 100 percent improved surge current capability and excellent thermal behavior. These features result in significant efficiency improvement and robust operation in solar inverters, Uninterruptible Power Supplies (UPS), 3-phase SMPS
Linear Technology Corporation has introduced the LTC4121, a constant-current/constant-voltage 400mA charger for Lithium-Ion, LiFePO4 and lead-acid batteries. The LTC4121’s high-efficiency, synchronous step-down topology accepts a wide 4.4V to 40V input. A programmable 3.5V to 18V battery charge voltage range with tight ±1% accuracy makes the LTC4121 suitable for a variety of battery chemistries. The fixed-output float voltage version, LTC4121-4.2, is
International Rectifier Corp. today announced the expansion of the power block family of devices with the introduction of the IRFHE4250D FastIRFET™ dual power MOSFET that reduces power losses by more than 5% at 25A compared to best-in-class conventional power block devices. The new 25V device is targeted at 12V-input dc-dc synchronous buck applications including advanced telecom and netcom equipment, servers,
If you happen to notice a cigarette butt in a gutter, don’t be too quick to scorn it as disgusting and useless. Well, yes, it’s still disgusting, but a team of South Korean scientists says it’s no longer useless. In fact, they’ve used the butts to create a material that could store energy in superconductors for use in all manner
Japan’s Panasonic Corp. says it will help finance Tesla Motor Inc.’s $5 billion battery plant in the United States. And at least one major investment firm reportedly believes the batteries produced at Tesla’s “Gigafactory” won’t just be powering electric cars. Panasonic, which already supplies batteries for Tesla vehicles, said July 31 in a joint statement with Tesla that it would
