a DC-DC boost IC can do this job. such as https://pdf1.alldatasheetcn.com/datasheet-pdf/view/266398/AIC/AIC1896PG.html
i'm working in www.hello-lighting.com, as a LCD/TFT engineer, any question about LCD/TFT, you can write to me. best regards! 在 2011年12月22日星期四 UTC+8上午12:16:16，euge euge写道： > > Hello, I'm going to try to attach a 7 inch tft lcd to the bone. > The first thing I met reading the screen datasheet is that I have to > feed all the bias voltages.to the tft myself. > So I have to put the AVDD, Vgth, and Vgtl (negative) , the backlight > led current, the digital voltage and the common voltage VCOM. > As if this wasn't enough the power has to be feed to the lcd sequentally. > I have seen some chips that help to do this task giving avdd,vgth,vgtl > and vcom like tps65105 but it's not in stock anywhere. > Anyone experienced with this knows alternatives?
