TPS65261-1: Fsw accuracy

Shuhei Goto

Part Number: TPS65261-1

Tool/software:

Hi team,

In D/S, Fsw seems to vary by +/-40kHz.
Is this accuracy due to the resistor error? Are there any other parameters that affect?

Best regards,
Goto

Dear Goto,

It's not only related with resistor error, but also related with the internal clock accuracy. Thank you!

Hi Lucia,

Thank you.
Is there anything the user can do to improve FSW accuracy beyond using low-error resistors?

Best regards,

Goto
