You'll also have to add frequency compensation to the feedback loop to cancel the phase shift of the LC resonant circuit otherwise it will oscillate.

Do any good sources for further reading come to mind on this subject?

How about a hysteretic buck?

 

Edit: Ronv, looks like our minds are in sync. I was writing my post when you posted your suggestion.

If you just want to experiment with switching regulators, below is a simple hysteretic (bang-bang) type regulator, which doesn't require loop compensation.
It uses a comparator to turn the MOSFET ON when the output voltage drops below the Ref 5V threshold and turns it OFF when it goes above the threshold.
This rapidly switches the MOSFET to generate the PWM signal and maintain the output voltage at 5V.

C3 provides a slow start ramp so the output doesn't overshoot.

C4 and R4 suppress spikes and oscillations at the switch output.

Noticed I used a low Qgate MOSFET to get good switching speed with a 2kΩ pullup resistor on the comparator output.

Disadvantages of this simple circuit are that you have no direct control over the switching frequency, which varies with load, and the output ripple can be higher than standard PWM designs.

 

Thank you to everyone that participated in this conversation. I learned a lot from the discussion.
