TPS92692-Q1: spread spectrum frequency

Part Number: TPS92692-Q1

Hello,

Are there any recommended spread spectrum frequency?
From the datasheet,  is the 100 Hz to 1.2 kHz ?
I would like to know the rule of thumb for deciding spread spectrum frequency.

Best Regards,
Ryuji

    Hello Ryuji-san,

    There isn't really any sort of rule. The range given is in case certain frequencies in that range may not be desirable in a system mostly. The most common practice is to set it in the middle around 600Hz and that is typically fine for most applications. But it can be changed if the EMI results need to be adjusted some.

    Regards,
