This is a very powerful buck converter design template tool that automatically computes all the parameters for a buck converter. No need to do long calculations as this template will give everything. All you have to do is to input your design requirements and that’s it.
You can use this template for either non-synchronous and synchronous buck converter topologies. There are notes in the design template so you can understand for what this parameter to. The good thing of this design template is that you can counter check the design equations.
Requirements for this Buck Converter Design Template:
A computer with Mathcad 14 or 15.
