If by "make" you mean create the schematic in LTspice and simulate it, then I would guess about an hour or two (mostly because this might be your first time using LTspice). If Linear has a part that already meets those…
LTspice [0] is an excellent (and might I add free) SPICE simulator. Linear includes proper models of the majority of their chip lineup, including LED drivers. Their power supply IC models are also excellent. You can…
