I am using an NHD-2.4-240320CF-CSXN#-F in my circuit. The backlight voltage, 3.1V, is much lower than the "typical" (about 20V) voltage of most TFTs I have used. Does Newhaven have a recommended backlight driver circuit?
The NHD-TFT-40 circuit works to drive the backlight, but it is not dimmable. I suspect this is because the FAN5333BSX in that circuit is a boost converter and, when supplied with 5V input, cannot buck that down to 3.1V.
