I have problem. I dont know how it happened but I have connected display with wrong polarity :-(
At least two components have been burnt - "C5" capacitor and unknown IC "U4" (voltage regulator?). I can't to make out IC inscription and value of capacitor. Anyone knows which are these components?
My display model is NX4827T043.
datasheet of MP3202: http://www.monolithicpower.com/desktopmodules/documentmanage/api/document/getdocument?id=1215
I have repaired my display. Thanks all for support. IC IL06EN is really step-up converter MP3202.
I didn't find IL06EN only IL06CG but it works fine. I found that schottky diode SS14 (D1) also has been burnt. I don't have similar diode so I replaced to trivial 1N4148.
My Nextion fried the backlight too. But I can't find IL06EN or IL06CG to buy.
Is there another IC similar to those used in Nextion?
I have ordered IC from AliExpress. You may find a many versions similar IC marked as MP3202DJ (IL6EB,IL6AH etc). I don't know differences between these versions but seems you may use any IC MP3202DJ.
Thank you Oleg, I will order from aliexpress
I bought the IC MP3202DJ but i received one IN6CB (with only 5 PINS), do you know if its the same?
No. It is not.
They might sent you the MP3202DG instead...
