A simple buck converter model that simulates.


CLK1 generates a 50% duty cycle digital signal.

M2 and R2 provide an inverting gate drive to control the gate of p-channel FET M1. D1 is a Schottky diode for current recirculation when M1 is off.

The circuit delivers about 16W to R_LOAD (2 ohms).

Run the time-domain simulation!

Would be very cool to build feedback around this model, replacing CLK1 with a PWM generator and some sort of voltage control loop compensation.


Like this?

Rough but ready to play with.
