Hello,
I have the following schematic for a 220v led strip dimmer,
it is driven with 3.9KHz pwm from an arduino.
there would be 2 problems:
the mosfet heats up (the led strip is ~ 140W / 220v)
the led strip brightness is responsive only for a small pwm range (10 steps of 255)
what gives the led strip sensitivity and how could I adjust it for using the full range of 255 steps form pwm ?
thank you,
regards,
Cosmin
