Simulation, high bandwidth communication and Ethernet integrated circuit (IC) solutions in the field of industry leaders Micrel company (MicrEL, Inc.) (NASDAQ: MCRL) today released a new high efficiency white light emitting diode (WLED) driver products series of products, the mobile phone call time was extended to an astonishing 32%. MIC284x solutions target mobile products of various types, including portable display backlight system, keyboard backlighting, mobile phone camera flash, intelligent mobile phone, portable media player, /MP3 portable navigation devices (GPS) and other portable products, in all these applications, save battery power is very important. MIC284x has now begun to bulk supply, 1000 batches of products, the starting price of $0.33. In addition, users can also visit the Swiss semiconductor company website (http://www.micrel.com/ProductList.do), online ordering samples. Andy, the director of the portable products group, said: "the display circuitry of a portable display and keyboard will waste a lot of battery power to produce a high voltage. The new white light diode driver architecture of the Swiss semiconductor company completely abandoned this defect, eliminating the need for up to five external components, saving up to 62% of the board space. MIC284x series is really changing the traditional white light diode driver circuit paradigm, providing the maximum efficiency, the smallest board space, is almost the most outstanding solution in the market today. The MIC284x series is an efficient linear white light diode driver product designed to drive 2 to 6 white leds. The chip uses a unique linear drive scheme, eliminating the need for switching components commonly used. This saves up to 62% of the board space. In addition, this high efficiency linear scheme extends battery life by up to 32%, providing more power for the large power screen. MIC284x series products through proprietary dynamic balanced matching (DAM (TM)) technology to ensure a consistent display brightness, this technology provides higher than 1.5% current matching and accuracy. The brightness of the white light diode is controlled by a Ultra PWM Fast (TM) or a 32 level single line digital interface. The Ultra Fast PWM (TM) interface is one of the most common control interface on the current market, the frequency control range, from 200Hz to 500KHz, when the backlight dimming duty cycle is less than 1%. MIC284x series of products using the 2mm x 10-pin Thin MLF (R) lead-free package, operating junction temperature range of -40 degrees C to +125 degrees C.
