Infineon Technologies introduces the new member of its XDP LED series, the XDPL8221 for cost-effective dual-stage drivers with advanced features. This device combines a quasi-resonant PFC and a quasi-resonant flyback controller with primary side regulation together with a communication interface. A comprehensive set of configurable protection mechanisms (standard and sophisticated) ensure safe, reliable and robust LED driver for a large set of use cases.The XDPL8221 combines advanced functions, such as multi control featuring constant voltage, constant current and limited power as configurable operating parameters. The result is a versatile, high performance LED driver. The performance of the XDPL8221 helps to design more efficient devices. This driver IC supports full functionality for both AC and DC input in the nominal input voltage range of 100 V AC to 277 V AC or 127 V DC to 430 V DC. Depending on the actual situation, the built-in digital control selects the best mode of operation. It can switch between quasi-resonant, discontinuous conduction or active burst modes.The XDPL8221 UART interface with a command set enables control of the functions of the device and provides status information. This enables numerically exchanged real-time data. This data can be used for monitoring or additional local control functions. This driver IC can be dimmed flicker free below one percent, while the current is still regulated with a high accuracy. The chip also offers a dim-to-off function to keep the device in a standby mode when the light is off with a low standby power (less than 100 mW, depending on driver design).Reduced bill of materials and increased flexibility minimize the overall system cost. The XDPL8221 comes in a DSO-16 package and, with a wide tool support, it is easy to design-in.Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Chips & Components last_img read more

first_imgLANGFORD, B.C. — British Columbia Premier John Horgan says Alberta may be the best place to boost refining capacity to increase a supply of fuel to the province.The price of gasoline has been rising in B.C. for the last month and the cost for a litre of gas in Metro Vancouver has been hovering around $1.70.Horgan says part of the problem is there’s too much demand and not enough supply, but adds that a 30-cent rise in gas prices in the last three months appears to be a result of gouging by oil companies.The premier says most refineries are close to the source of the product and because Alberta has more expertise, that may be the better location for new refining capacity.In 2014, B.C. newspaper mogul David Black had proposed a $13-billion oil refinery on B.C.’s northern coast, and Horgan says he encourages Black to bring the plan forward to go through the regulatory and environmental process.Metro Vancouver drivers pay over 50 cents a litre in taxes to the federal and provincial governments and for carbon and transit taxes.

first_imgProfessor Shamnad BasheerTwitter Intellectual Property Law specialist Shamnad Basheer passed away in a freak car accident in Chikkamagaluru district of Karnataka. The 43-year-old scholar, who was the founder of Increasing Diversity by Increasing Access (IDIA, was missing for the past four days after he had gone to Baba Budan Giri from Bengaluru for a health check-up on July 28. Shamnad was scheduled to return to Bangalore on Monday (August 5) but remained untraceable. His family members filed a missing complaint on Wednesday. The search party, along with the local police, was unable to locate his car initially due to heavy rains and thick fog in the area but later found it parked away from the road.Although an investigation into the incident is underway and the cause of death is yet to be ascertained, the Superintendent of Police of Chikkamagaluru, Harish Pandey, told The Hindu, “It seems like he slept in the car, switching on the heater. Inhaling too much of carbon monoxide could be the reason for his death. There are chances of a short-circuit too.”The post mortem will be conducted on Friday and his mortal remains will be taken to Kerala for the last rites. “We are waiting for the post-mortem to be done to obtain clarity on the death. Foul play is being ruled out because the car was locked from the inside and the key was in the ignition,” said Pandey. Professor Shamnad opened a new portal and paved the way for the production of cancer drugs at minimal cost in India. The legal scholar also argued that India has the potential to produce medicines for diseases, including leukaemia, without the application of global patent law.In a landmark battle with the Swiss drugmaker Novartis in 2012, Shamnad had argued before a two-judge bench of the Supreme Court that the company was trying to sell Glivec, a cancer cure medicine at a distinct twentyfold markup. The medicine is sold by the generic drug makers in India at a very low price and Novartis had tried for a patent over Glivec, which was rejected after which it approached the apex court.Shamnad, who is from Kerala’s Kollam, completed his graduation from National Law School of India University, Bangalore, and did his post-graduation from the University of Oxford. He was also the Frank H Marks Visiting Associate Professor of Intellectual Property Law at the George Washington University law school in Washington DC.He started his career with an intellectual property law firm in Delhi, Anand and Anand. He founded IDIA in 2010 with a vision to help the students from rural and disadvantaged backgrounds to crack law entrance exams and provide them with quality education.In 2008, he joined the National University of Juridical Sciences (NUJS), Kolkata, as the first Ministry of Human Resource Development Chaired Professor in Intellectual Property law. He was awarded the Infosys Prize for Humanity in recognition of his outstanding contributions to legal issues.last_img read more

first_imgPeople who start their day with a heavy meal are more likely to weigh less, according to scientists who confirm the age-old adage that one should breakfast like a king and dine like a pauper. A study of 50,000 people found that those who made breakfast their largest meal of the day has a lower Body Mass Index (BMI) than people who waited until supper, even when they ate a similar number of calories.Researchers from Loma Linda University School of Public Health in the US also found that extending the time between the final food of the day and breakfast was also associated with lower BMIs.”Eating a large breakfast reduces hunger cravings, especially for sweets and fats thus counteracting weight gain,” said Hana Kahleova, lead author of the study published in the Journal of Nutrition.”Regular breakfast consumption seems to increase satiety, reduce total energy intake, improve overall dietary quality, reduce blood lipid and improve insulin sensitivity and glucose tolerance,” Kahleova said.”On the other hand, eating meals in the evening generally has the opposite effects, all of which adversely affect body weight,” she said.Scientists suggest maintain a healthy weight people should eat breakfast and lunch, skip supper, avoid snacks, make breakfast the largest meal of the day and fast for up to 18 hours a night.last_img read more
