Simple Buck Converter nn

This circuit illustrates the basic operation of a DC-DC step down buck circuit. The diode and transistor elements are modeled using ON/OFF resistances. These elements help focus attention on the duty cycle. Run the simulation. The circuit is configured to provide 5V. 1. Adjust the value of the capacitor C1 and observe the output voltage ripple. 2. Slowly adjust the R_load resistor to change the load current.
