The special company (Semtech) rises Released the newest depressurization type stabilizator component today. New SC283 whether global minimum the intersection of 1.8A and double channel support some the intersection of power and stabilizator, adopt ultra light ultrathin 2 x 3 x 0.8mm, 18 pads of MLPQ capsulate, include two depressurization stabilizators. The output of each stabilizator can be set up independently through VID base pin, has saved two pairs to connect feedback resistance, have further reduced the area of the power module. SC283 POL stabilizator adopts stationary 2.5MHz switching frequency, so can adopt the minimum chip inductance, have offered the subminiature solution of 111mm2.
It is said that the reputable products marketing manager Alan Burchfield of the special power managerial body rises: “Industry have other rival can offer so light the intersection of 1.8A and pair of area step down stabilizator. Realize this kind of amazing ultra small area does n... Read more
ADI introduces the driver in a poor light of ADP8870 white light LED charge pump recently, it can make the power consumption of the battery-driven handheld apparatus reduce by up to 45%, and does not influence revealing quality. ADP8870 collects three key functions in an organic whole: Programmable LED charge pump driver in a poor light; Used for the phototransistor of autocontrol LED luminance inputting; And is used for managing PWM (puls e-width modulation) of the output current proportion Input. So, it can change current strength automatically according to environmental illumination intensity and white light composition of the display image, thus reduce the power consumption by a wide margin. ADP8870 Yes this function of automatic performance, do not need to make use of processor to control the phototransistor, therefore can further reduce power requirement and simplify and design portably and in a poor light.

According to EE Times, the expectation of U.S.A. market survey Company ICInsights, on the basis of extensive semi-conductive product line and expansion plan, South Korean Samsung is expected to surmount Intel in 2014, include the first high semi-conductive enterprise as the whole world.
ICInsights admits, if say from 5 to 10 it seemed a bit funny that Samsung will exceed Intel. But between 1999 and 2009, three stellar compound annual growth is 13.5%, Intel is only 3.4%. Calculate, three stellar semi-conductive sales amount would surmount Intel in 2014 according to this growth rate.
In these decades, Intel is the first largest semi-conductive manufacturer in the world, mainly benefit from its leading position on the market of microprocessor. Samsung has already occupied the position of second in market for many years too. Samsung is a leader of market of DRAM and NAND flashing memory chip, the scale in the field of microcontroller is very large, and this company is expa... Read more

Apple should consider oneself build pieces of fab, not because is joking, but can be regarded as a suggestion. Even can bet Steve Jobs will certainly have considered this.
The apple should be considered and build one’s own fab, produce A4 processor that iPad and iPhone use, therefore the improvement that one’s own processor characteristic can be constant.
Obviously, building fab should melt a lot of qian, the apple regarded oneself as a traditional OEM in so many years, buy the component, assemble them into products or systems and and let its chip supplier undertake the risk of fab, but why can’t the apple change the thinking
Because the apple is different from traditional OEM, its products are iPod, iPhone, iPad,etc., it is more in the future and is expected. Like Cisco and IBM, the apple can be designed personal ASIC. And the apple is own have been purchased P.A.Semi and Intrinsity separately to promote ASIC designed capacity of it.
