Diodes Incorporated (Diodes Incorporated) introduced a linear constant current LED driver AL5809, products using a robust double-joint PowerDI-123 package, providing more accurate affordable linear constant current LED driver solutions. AL5809 having up to 1.2W of power, 20ppm / ° C excellent temperature stability and high power supply rejection ratio, providing ± 5% tolerance over a wide temperature range, effective greatly simplify for LED light board, LED lights program strings and low current replaceable lamps and other products.

AL5809 temperature range of -40 ° C to + 125 ° C, the operating voltage range from 2.5V between the two joints to 60V, and offers a variety of fixed output current options, eliminating the external current set resistor. Fixed output current options PowerDI-123 package includes 15mA, 20mA, 30mA, 40mA, 50mA, 60mA, 90mA, 120mA and 150mA; another SOD-123 package, the current output options there 15mA, 20mA, 30mA, 40mA and 50mA .

AL5809 addition to being able to meet the circuit design requirements for streamlined linear regulator (such as eliminating the inductor or an external resistor), it also provides other functions as well as drive the low and high side of the LED light strings ability overtemperature protection. Compared to similar products on the market and discrete circuit design, this simple operation, material costs affordable compact LED driver can provide more accurate and more comprehensive performance.

Diodes Incorporated linear constant current LED driver AL5809 to ten thousand for bulk shipments, providing SOD-123, PowerDI-123 and high current 60-150mA PowerDI-123 variety of package options.

Samsung Electronics and the world’s top memory chip maker SK Hynix plans to invest 19 trillion won in 2015 for the development of the chip, the investment plan is higher than last year’s 17.7 trillion won investment funds chips. According to the US official said one hedge fund, Samsung Electronics and SK Hynix hope that through this 19 trillion won investment, improving product mix to adapt to market conditions, adjusting the supply and demand balance of the market.

It is reported that some hedge funds and investment institutions are optimistic about the future development of Samsung Electronics and SK Hynix. According to the investment plan, Samsung Electronics plans to invest 3.5 trillion won, SK Hynix plans to invest 5.5 trillion won. Samsung, an official said Samsung’s sales growth in 2015 will be reduced to a minimum. Samsung does not want to have an impact on its chip spending their overall spending levels. The official said that Samsung plans to flash-memory and processor chips restructuring, adjust product line is flexible.

Samsung’s chip in 2013 to R & D investment of 12.6 trillion won, has invested 1.385 billion won in 2012, 2011 has invested 1.303 billion won. SK Hynix is currently no plan to increase investment in the first half of 2015. For SK Hynix, the supply and demand is positive, the traditional enterprise server and PC demand remains strong.

According to a person familiar with SK Hynix officials said, SK Hynix plans to invest 300 billion won in research and development M14, the new plant will be equipped with new technology and thinner.

SK Hynix investment funds last year, about 4.7 trillion, which SK Hynix CEO, said the company this year will give priority to further strengthen the competitiveness of memory chips to improve the stability and quality of the product.

According to reports, SK Hynix 76% of global annual sales of DRAM chips, 21% NAD chip, 3% non-memory chip. According to the research firm’s data show, Samsung Electronics, SK Hynix, Micron Technology US market accounted for 93% of global chip.
