ADI Company introduces the lighting supervising system of the adaptation, in order to raise the power efficiency of the walkie electronic product
Global and leading high-performance SIGPROC signal processing solution supplier, putting out one newly efficient and customizably reveals that manages the solution & mdash; — ADP5520 lighting supervising system, can improve cellular telephone, personal navigation aid and display quality of the media player, and lengthen the battery life-span. To a large number of demands of battery power consumption on the basis of the display screen of the portable electronics, and consumers are to the demand for jumbo size and more high-quality screen while watching the content with abundant color, considering the item as the increasingly important design in power efficiency of the display system.
ADP5520 lighting supervising system of the single chip is adopted " Intelligence " Lighting control technique,it is all right automatic detection ambient brightness,and adjust to last luminance illumination the changes of environment, thus can make the battery power consumption reduce by 20%. Adaptation ambient light manage characteristic, can require according to illumination of configurated, self-regulate on crossing dark screening, so can reduce in a poor light to control to dawdle the processor, thus reduce current consumption, in order to lengthen the battery life-span. In addition, ADP5520 can scan to the keyboard of the processor and the common I/O sub system function is controlled, further reduce the systematic power consumption, and increase the available bandwidth of the processor.
Folding or the slide phone design engineer can utilize the lighting supervising system of this high integration density, make the intersection of mobile phone and axis of rotation / the intersection of rack and the intersection of control line and quantity of reduce 14 to from 53, this reduce, lie in cost of system in a poor light of LCD by the display unit notably, and improve reliability. In the typical application of the mobile phone set, ADP5520 integrated control, lighting sensor, LED indicating device of key field on single chip, and LED power in a poor light, it can offer the programmable file with margin of the minimum software, in order to control the LED density, opening/closing timing, cubic luminance gradation zone algorithm (or the square-law) in a poor light And the luminance reduces the timer.
