Display backlight schematic for the Samsung SM-A22 5G, a 5.25 MB PDF sheet. It shows the backlight driver, the boost inductor and diode, enable signals and the lines running to the panel connector.

Open it in any PDF viewer and confirm the handset is the 5G version of the Galaxy A22 before trusting component designators.
