I have an existing WLED pcb I made, but want to make it lower power so shutting off the led strip when not in use and adding a switching reg. I want to keep the board size small so was wondering if anyone had tried putting a N-channel Mosfet to switch the GND on leds to shut them off. (rather than using relay on 12v)
has anyone tried this? I could use P-chan on the 12V side but that needs a few more components so would prefer n-channel option.
