Buck Converter DC/DC_pronto

This circuit illustrates the basic operation of a DC-DC step-down buck circuit. The diode and transistor elements are modeled using ON/OFF resistance. These elements help focus attention on other salient variables in circuit: duty cycle, L, C, parasitic resistances, and load current. The circuit provides a great way to understand some of the behaviors of this very important topology. Run the simulation. The circuit is configured to provide 5V.
