White Led Driver 0.9

Asian currencies drop as stocks fall

Asian currencies declined this week, led by the biggest five-day drop in Indonesia’s rupiah this year, as concern that Greece will default on its debt reduced demand for emerging-market assets.

The MSCI Asia-Pacific Index of regional stocks fell to its lowest level in almost three months as overseas investors sold US$1.5 billion more equities than they bought this week in South Korea, Taiwan and Thailand, exchange data showed.

“The main driver for the decline in Asian currencies has been the unfolding European debt crisis,” said Mirza Baig, a Singapore-based currency strategist at Deutsche Bank AG.

The rupiah slid 0.9 percent this week to 8,596 against the US dollar in Jakarta on Friday, according to data compiled by Bloomberg.

The New Taiwan dollar weakened 0.6 percent to NT$29.000 against its US counterpart, its biggest weekly loss since February, Taipei Forex Inc data showed. It reached NT$29.005 on Friday, the lowest level in three weeks.

Malaysia’s ringgit lost 0.4 percent to 3.0315 and the Philippine peso weakened 0.7 percent to 43.60.

The Bloomberg-JPMorgan Asia Dollar Index, which tracks the region’s 10 most-active currencies excluding the yen, fell 0.1 percent this week and touched 117.85 on Friday, the lowest level since May 26.

“Concern about global growth and the euro debt issue is all coming together and weighing on investors’ minds,” said Prakriti Sofat, an economist at Barclays Capital in Singapore.

The Thai baht touched its weakest level in more than three months on concern elections scheduled for July 3 would spark protests. The vote will pit Thai Prime Minister Abhisit Vejjajiva’s Democrat party against the Pheu Thai party led by Yingluck Shinawatra, the sister of former Thai prime minister Thaksin Shinawatra, who was ousted in a 2006 coup.

The baht dropped 0.6 percent to 30.57 per US dollar this week and reached 30.66 on Friday, the lowest level since Feb. 28.

Elsewhere, the South Korean won rose 0.2 percent to 1,081.50 against the US dollar this week, the Singaporean dollar dropped 0.2 percent to US$1.2346 and the Indian rupee declined 0.3 percent to 44.87 per US dollar, according to data compiled by Bloomberg.

Meanwhile, Taiwanese government bonds had the biggest weekly advance in three months, with 10-year yields reaching a one-week low on Friday.

“Taiwan’s government bonds had a volatile week, as stocks slumped and investors fled to safety,” said James Wang, a fixed-income trader at Yuanta Securities Co in Taipei.

Fit the American semiconductor full of trees and introduce LED driver

The global leading supplier of the advanced power supervisory control solution fits the American semiconductor full of trees listing coaxiality of ON Semiconductor American Nasdaq: ONNN Introduce NCP5603- – new white light LED driver, used particularly in driving high light LED in the flash-light or blinker is employed in camera – mobile phone and other walkie consumption electronic products.

NCP5603 adopts structure of the charge pump and two pieces of external ceramic electric capacity to offer the power to change, and does not need to adopt and is used in the stored energy inductance of large volume that the power changes. Its DFN-10 encapsulated size is only 3 mm x 3 mm x 0.9 mm, with the definite surface area, are suitable for the electronic application of walkie consumption with thin appearance.

This new LED driver adopts 2.7 volts V The battery voltage to 5.5 V range offers the constant voltage for load. 1X, 1.5X and automatic work pattern of 2X its, peak efficiency reachable 90%. Especially suitable for driving low cost, low power to pay attention to lengthening high-current LED of the battery life-span while employing. This device exports up to 350 milliamps mA Impulse current,high light every one W when lasting drive LED of the power, therefore can improve the characteristic of the camera blinker, obtains the more high-quality picture. The characteristic of this device also includes PWM/EN inputs, is suitable for the requirement of adjusting luminance.

NCP5603 does not need stored energy of external inductance, so can be regarded as the direct current of low-cost, small-scale boost – direct-flow converter, bias the audio amplifier to offer the constant voltage of 4.5 V or 5 V in mobile phone, MP3 player or digital camera the highest in volume.

Fit the American semi-conductive power full of trees and change the executive vice president Andy Williams of product division and say: “Fit the American semiconductor full of trees and expand the white light LED driver product series with NCP5603. This high-efficient solution based on charge pump, direct against the small-scale mobile phone limited in volume, NCP5603 is the first devices of this series. This series of products have offered the high-efficient charge pump solution to engineer, output current control, short circuit protection, in a poor light to match, have flexibility of maximum with the intersection of camera and high-accuracy electric current of blinker. The outer cover of this series of products adopts slim DFN smallly and exquisitely to capsulate in addition.
