TPS22969: Can VBIAS and VIN be same - 5V ?

Part Number: TPS22969
Other Parts Discussed in Thread: TPS22990,

Hi,

i am using above switch in the power supply section.

Can VBIAS and VIN be same as 5V? Is there any issue for that.

I have only one supply available.

  • Hi Joseph,

    There shouldn't be any issue with this configuration, make sure that enable is low if your input supply is in scenarios where it can be plugged in/out to prevent abnormal startup behavior.

    If you're looking for additional protection and status features, I recommend taking a look at the TPS22990, which offers power good and a smaller package than the TPS22969.

    Thanks,

    Arthur Huang
  • Thanks for your quick reply.

    In our case both VBIAS and VIN are ramping same way.
