    PI Controller DC-DC Buck Converter with PIC16F877A

    there is no output signal on osilascope but i will change the PIC and i will test again (tomorrow) For example there is an input voltage of 24 volts and I want to lower it to 18 volts and i provide it with buttons then i change the value of the load resistor but the output voltage is remain the...

    Buck Converter with PİC16F877A

    i tried but i failed can you create a schematic? i didn't yet buy components so its doesn't matter if it is works in isis then i will buy the components btw i tried with IR series and i tried with transistor but its doesn't work... (
