TPS62812-Q1: Spread Spectrum Clock frequency variation

Part Number: TPS62812-Q1

Hello support team,

Please tell me the maximum switching frequency including variation in the case of SSC enabled version.

I plan to use this IC with an internally fixed 2.25 MHz configration.

    (Maximum switching frequency = Maximum fixed frequency 2.475MHz + SSC maximum variation)

I would like this information to calculate the buck ratio for PWM operation.



  • Hi, 

    The value suggested in datasheet is for maximum variation expected from SSC enable feature. I don't think it will vary for than 288kHz.

    You can evaluate maximum frequency variation with this value for worse case analysis..

    Best regards,
