That’s similar to the Red dimmer. You can see the current waveforms into a resistive load I measured here.
I’m curious what the fascination is with building leading edge dimmers using MOSFETs which are only needed to build trailing edge dimmers. Leading edge dimmers could be made with cheaper TRIACs. LEDs are generally happier with trailing edge dimming and when the hardware has the capability to do trailing edge it seems odd it’s not implemented.
