TPS53915: Compatibility with TPS53515

Part Number: TPS53915
Other Parts Discussed in Thread: TPS53515

Hello Support team,

Since we are facing the delivery issue of TPS53515 now, we want to study TPS53915 as an alternative option.

Is it possible to apply TPS53915 instead of TPS53515 without PMBus?

If we don't use PMBus, can we connect SDA/SCL to GND?

If there are any concern about the replacement, please let me know.

Best Regards,

Hirokazu Takahashi

  • Yes, you can used the TPS53915  if the 400kHz default switching frequency is not a showstopper. 

    The only method to change the fsw from  400kHz  on TPS53915 is via PMBus. 

    If PMBus is not used or needed, just ground the SDA and SCL pins. .
