RA8875 to 7" TFT Backlight voltage

by emills on Wed Feb 07, 2018 10:25 pm

I wish to drive your 7" TFT (2353) with RA8875 (1590), but wanted to check the backlight voltage was compatible. The description of RA8875 states that it drives the backlight at 24v, where as the datasheet for the TFT states a typical voltage of 9.9V with a max of 10.5V (https://cdn-shop.adafruit.com/product-files/2354/adafruit_SPEC-YX700WV03_REV.A-787880.pdf pg10). You state however these are compatible. Is this correct?
