Tool/software:
Hi expert,
Customer used TPS62827 for 4Vin to 0.85V/4A application and have a question regarding Fsw. They want to know if any problems from their design.
They did test to measure Fsw in different loads. Our DS only has typical value 2.2Mhz and looked at fig. 8-27, we can only tell the trend of the Fsw. We put Fsw from DS fig8-27 in the table left hand side as a reference.
From current greater 3A, the Fsw seems getting smaller. However, check out customer measurement data on the table right hand side, we saw the Fsw is getting higher.
Could you please advise if the result is good and how to explain the trend is different between our DS and customer measurement?
Regards,
Allan
