About a 1A limit.The trick to this circuit is finding a way to change the PWM on the gate of the MOSFET based an error signal. A square wave -> integrator = Triangle wave. T wave compared with an error signal. This gives a changing PWM. The desired voltage is set by voltage source in upper left corner. Reducing Inductance decreases ripple (20 mV) but reduces current output. Increasing cap reduces ripple but sim goes unstable. This was fun!
