SMPS Buck Converter Design Example

Recording Date: 09/05/2006
Duration: 12 min


This course covers a design example of a simple Buck DC-DC converter. In this example we will calculate the required inductor and output capacitor specifications. We will then determine the input capacitor, diode, and MOSFET characteristics. With the selected components, we will calculate the system efficiency and then compare an asynchronous buck converter to a synchronous buck converter.
