take a look at the various schematics available for tablet reference designs etc. etc. you want something like a SY7208 see http://hands.com/~lkcl/eoma/TABLET162_20121110.pdf page 7 and make sure it's providing enough current.
The link is incorrect. Do you want to say this link?:

I have seen that this is more recent:

What you recommend me?
please for goodness sake read the next update when it comes out, please for god's sake don't go searching on digikey, pick the first random convenient IC and expect to be able to have what you design made up in even a small volume at anything approaching a reasonable cost. it's very very easy to design ultra-expensive products.
take a look at frida's LCDs, we have the advantage of being in touch directly with marco, the possibility of group buys, etc. etc. datasheets all here: http://rhombus-tech.net/suppliers/shenzen/frida_lcd/
I think that most components are in large quantities in China:
- Linear potentiometer (trigger) and joystick -- Favor Union/Polyshine (a Hong Kong company). MOQ is higher, but price is very good. - TFT + RTP -- Frida. - Battery -- Kamcy (a Chinese company). A lot of chinese companies sells this battery. - EEPROM -- The same that you use on laptop/tablet. - STM32F072 -- The same that you use on laptop. - Audio IC -- The same that you use on laptop. - TS4408A button -- a lot of stores sell its in Aliexpress/Alibaba with good prices: https://aliexpress.com/af/4mmx4mmx0.8mm.html - SKRTLAE010 button -- you use it on laptop. Have you found a chinese replacement? - USB 2.0 -- you use it on laptop. Have you found a chinese replacement? - PMIC -- you use it on tablet. - MicroUSB, microSD and Audio Jack -- you use it on laptop (Runde). - XPT2046 -- a clone of ADS7843. A lot of chinese stores sell it on Aliexpress/Alibaba.
What do you change?
Thanks!
