Introduce Lenovo Debuts 5 Inch Vibe X Smartphone

Introduce Lenovo Debuts 5-Inch Vibe X Smartphone . Lenovo unveiled its new Vibe X, a fairly clear-cut smartphone, at IFA Berlin on Thursday. The 5-inch apparatus arrives with a 1,080p IPS display, a quad-core, 1.5GHz processor, a 13-megapixel camera (coupled with an oddly powerful 5-megapixel one on the front), 2GB of recollection and 16GB of storage. The specs are admirable, but they aren't the best out there. although, add in the premium polycarbonate body — which is just 6.9 millimeters thick and weighs about a quarter of a pound — and Vibe X becomes a solid lightweight competitor in the crowded 5-inch Android arena. On the programs edge, just like most of its new brethren, it sprints Android 4.2. The Vibe X will never reach European or the U.S. coastlines, we've been notified. Price and release designated day are not yet available.

AOC AL512 – AOC AL513 – 15 Inch TFT LCD monitor – Circuit diagram

DC-DC CONVERTER This block provides adjustable output voltages of 9.2V, -6V, 18V and 3 to 4V for the panel. It consists of a Q114 transistor and power switch IC I108 (AIC 1526-1). When DC_ EN signal is high, then Q114 is activated and send one signal to activate I108. At this time I108 will send 200KHz 12V PWM to Q106, Which is connected with L111, Q106, D203 and C308, to boost 5V to 9.2V. And I108 offers the adjustable voltage of 3V to 4V. By sending out pulses from pin 2 and pin 16 of I108 to double voltage circuit consisting of C301, D201, D202 and C303, leaner regulator with Q105, would output –6V, 18V output id created, according to the rule of –6V creation. Inverter In order to drive the CCFLs embedded in the panel module; there is a ROYER inverter to convert to convert the input 12V up to hundreds of AC voltage output.  The inverter is formed by symmetric, in order to drive the separate lamp modules. The input stage consists of a PWM controller, buck choke, and switching MOS...
