TPS92520-Q1: Switching frequency tolerance

Zhang Jason
Prodigy 175 points
Part Number: TPS92520-Q1

Hello,
What is the tolerance of switching frequency? How to calculate this?
For example, if CHxTON=000111, typ switching frequency is 437kHz, and how to calculate the min and max switching frequency?


Thanks.

    Hello Jason, 

    This Ton calculations are in the datasheet. 

    Keep in mind that the not a fixed frequency part and is called a pseudo-fixed frequency.  The tolerances can be fairly wide based on operation conditions and part to part variation.  We do give a range based on a couple of Tonx values, which is in the datasheet.
