Title: Help to choose Backlight LED driver
Post by: moiatto on March 10, 2024, 08:04:16 PM

I have to drive, for a 5" 800x480 TFT IPS 1000nits RGB 40pin, the backlight which requires Vf=30V, If=40mA (array of 2x10 white LEDs).

Can you help me find the right led driver?

Chip used: BT817Q

Hello,

Thank you for your question.

We utilise the following LED backlight drivers on our development modules, maybe these would be suitable for your application:
