Determining Average Switching Frequency
To determine the switching frequency for a design, you must have a detailed understanding of the data
input values to the circuit. The following guidelines are meant to represent worst-case scenarios so that
they can be generally used to predict the upper limits of power dissipation. These guidelines are as
follows:
