An Infineon ILD6070 driver. This is like any other buck driver that accepts a PWM signal, and doesn’t provide any type of feedback loop. It just does whatever the PWM signal tells it to do.
Did you try the suggestions I made to eliminate the flashing?
I put the digitalWrite(ledpin, 3) before the pin is set to output and there wasn’t any change. Still a blink before going to mode 2 (30%) and then no PWM output. Any other ideas?
You need to write the pin to 0 (low output)
Ok, I understand now. I tried that just now and no change.
sounds like it must be the hardware startup timer that other users have mentioned then
