Hi Team:

I have a question about TPS53219 pre-bias function.

Does TPS53219 operate properly even if there is a pre-bias voltage of 1.25V in the output before turn on the power?

Thanks for your help and time.

Hi Redick,

TPS52319 can support pre-bias start up. Please review attached TPS53219EVM user's guide figure 12. If 1.25V is lower than the output setting voltage, TPS53219 can operate properly.

Thanks,
