In the circuit, a 5V DC input is switched using a 1 kHz square wave, producing a pulsed signal. This signal is filtered using an inductor and capacitor to produce a lower, stable DC output of around 2.25V. Buck converters are efficient and widely used in power supply applications for electronic devices. | Electronics Education | Facebook

This simulation demonstrates the working of a Buck Converter, a DC-DC step-down converter used to reduce voltage efficiently. The input is a 5V DC supply with a 1 kHz PWM signal controlling the switching transistor. The circuit includes a 100 Ω resistor, a 1 H inductor, a 10 µF capacitor, and a 1 kΩ load resistor. The PWM signal (orange waveform) drives the switching, while the blue waveform shows the smoothed output voltage, which is around 2V, lower than the input, indicating proper buck conve
