DC Buck Converter, DC-DC 12V/24V to 5V 5A Step Down Power Source Module Buck Module Buck Converter Module

in this video we're gonna talk about the buck converter circuit so let's draw the schematic of the circuit the first thing we need is a voltage source now we're gonna use a battery for that next we need a switch which we'll call s1 and parallel to the battery we need a diode and then we need an inductor and a capacitor the purpose of the capacitors to maintain a relatively stable output voltage across the load resistor so this is going to be RL C and D 1 let's use a 12 volt battery in this example so this is the buck converter circuit this circuit works by reducing the voltage at the input now there are a lot of other circuits that can reduce the voltage such as a voltage divider circuit using two resistors or even Zener diodes and linear voltage regulators you can use them to not only reduce the voltage but maintain a constant output voltage as well but those types of devices they redu
