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