I have a circuit that I believe will work, but I was hoping someone could double check?
Removed image to make room for edit. - Original schematic
The load has a resistance about 2.525Ω
Assuming that the CVCC is required, would my circuit work?
Edit: I edited my circuit design, could it work better now?

Edit: Edited schematic to reflect changes.
Also, the purpose of this circuit is switching. When the photo-interrupter beam is intact, the load gets no current. When the beam is broken, the load gets current. Or, that's the idea here.

@CopperMaze, Thanks for the suggestion!
Edit: Edited schematic to reflect suggestions, and resolve mix-up.
Edit: Added freewheel diode, re-added R3 to soften the inductor impact on the MOSFET.
Edit: Changed freewheeling diode to Shottky diode as suggested.
