TPS56C215: MODE setting for 1200 kHz

Part Number: TPS56C215

Hi team,

We want to set 1200 kHz switching frequency for TPS56C215, but found that the recommended setting of Webench is different from the setting in datasheet as shown below.
Could you comment which is correct? Thank you!

Datasheet setting:

  • Sam, Datasheet should be accurate, and I think webench should be right as well, because mode pin is decided by the ratio of VCC with resistors dividers, and actually it should be a tolerance. You can run the model to check Frequency right or not to double check. But for schematic design, recommend to follow datasheet, close to the table value.
