I cannot get the output voltage low enough.
When the PWM output pules from ATtiny is 200ns, the power FET is on for 1us. This results in a too high voltage (appx 10V) for my need (8.5V).
I measured input to driver at TP410 (CH1), output from driver at TP411 (CH2) and Power switch at TP408 (CH3). I will try to attach the scope traces here.
