Fit the American semiconductor full of trees and win the famous reward of e-magazine industry
Recently, the American semiconductor (ON Semiconductor) full of trees is fitted Announce ESD9L and NCP5810 obtain famous reward of two items of industry that China leads the e-magazine.
ESD protective device ESD9L is got " today the electron " the magazine one " The products of 2007 " Reward, and double-output direct current - direct current (DC-DC) The converter NCP5810 is in " portable product design " magazine " Face the applied power management reader's investigative action of the portable products " Middle to compete for, and crowd the top five of comprehensive rank of body more than 30 competition products.
The intersection of products and award authorize, have maximal technology or employ and improve 2007 in " the today electron ", innovation designs or competes with market the products to compare the products with higher cost performance. " portable product design " has presumed very rigorous evaluation standard for its investigative action reward of readers of power management of 2008. The evaluation of the products is on the basis of 12 criteria, including the characteristic, power consumption, software compatibility, it is apt to design the intensity, reliability and reference design etc..
ESD9L and NCP5810 which fit the American semiconductor full of trees rely on high performance, high cost performance, innovative technology and easy to design, break out from the candidate products, obtain the special honours.
ESD9L is the single wire ESD protective device of paragraph, offer picofarad 0.5 (pF) Low clamping voltage with leading electric capacity and industry. This device adopts ESD in the industry to protect applied and minimumly and capsulate, is very suitable for mobile phone, MP3 player, personal digital assistant (PDA) And the high speed data line protection of portable application such as the digital camera.
In order to overcome the limitation of traditional silicon TVS diode, fit the American semiconductor full of trees and use the breakthrough technology, integrate intrinsic barrier diode and high-power TVS diode of the ultra low capacity on the single bare chip, can be used as the high performance slice ESD protects the solution. Person who integrate this ESD protect technological platform keep traditional the intersection of diode and technical remarkable clamping and low to leak the characteristic, TVS of silicon, already, reduce the electric capacity from 50 pF to 0.5 pF by a wide margin. 0.5 The total electric capacity of pF makes ESD9L suitable for USB2.0 ( 480 Mbps) at a high speed And the high definition multimedia interface (HDMI) ( 1.65 Gbps) Wait for high-speed application. According to the standard of IEC61000-4-2, 15 kilovolts (kV) that ESD9L will be input ESD waveform being counted with nanosecond (ns) Inner fast clamping is to less than 7 volts (V) . The leading industry of voltage characteristic of this clamping, guarantee to offer protection for most responsive IC.
NCP5810 is 2 watts (W) offered the positive and negative output voltage for one section Double-output DC-DC converter. The intersection of output voltage and accurate high conversion frequency of device this and small dimension capsulate enable their suit for the intersection of active matrix and organic luminescent diode particularly ' Active matrix OLED or AMOLED) The display of the faceplate drives and supplies power, for walkie application new developing display technology.
The latest display technology, OLED of active matrix, have the intersection of display unit and manufacturer of drib only batch productino this year and next year, but compared with present LCD display technology, it offers better color to compare with and the video sows quality, but add the challenge of power management for project engineering personnel. For example, in view of AMOLED display screen being very sensitive to the change of the service voltage, fitting the American semiconductor full of trees designs NCP5810, only offer the accurate feedback voltage of 1% of the voltage tolerance and fast circuit transient responses, and is inputting voltage fluctuation as 500 millivolts (mV) When, the transient overshoot voltage is only 4 mV.
In 1.75 MHZ (MHz) The whole power efficiency is up to 85% of the characteristics under the oscillator frequency, NCP5810 double-output direct current - direct-flow converter has offered the most excellent characteristic in the industry. For the fine and thin appearance of the complementary AMOLED display screen, the convertible high frequency to 1.75 MHz of this converter, can use volume minor inductor and ceramic output capacitor. Thick to capsulate while being ultrathin 0.55 mm its, make NCP5810 used in the thinnest walkie product design. In addition, its deenergization function under the shut-down mode, will let out revealing the electric current will be limited in 1 microampere (uA) ,Have saved the battery power under the shut-down state. NCP5810 also has crest current restrictions and heat of Cycle by Cycle that shut down and protect the function.
