Buck converter controlled by a microcontroller

[salahaldeen]

Hello,

Here is a graduation project to have 10 volt input into a buck converter (step down), where the output is connected to the microcontroller through ADC as a feedback, so any variations of output (load change or whatever) than stated by the reference set by the user the microcontroller should adjust it and display output signal and status on a graphic LCD.

Anyway, I hope you can suggest a good buck converter design where the microcontroller can control the output through the pulse generated for switching of the converter.

Many Thanks

Why would you reinvent the wheel? There are a lot of chips out there with everything built in. All in one chip converters with high stability and no fuzz, why make something more expensive, complicated and less reliable?  :-\
