MC13783 buck and boost inductor sizing

Posted: 18 Mar 2010     Print Version  Bookmark and Share

Keywords:MC13783 buck  boost inductor  optimised switching regulator 

This application note aims to provide a method of choosing the size of the inductors for the optimised switching regulators vs. the current consumption of the application. This will allow to optimise the size and the cost of these components.

The buck converter architecture used for the MC13783 is a simple PWM voltage mode control topology using a clock, which is 32 times the crystal oscillator clock of 1.024MHz. Pulse skip mode is supported and would occur at a current level determined by the external L, C components, and the input and output levels.
