TPS63031: Start Up at Pre Bias condition

Part Number: TPS63031

Dear Specialists,

My customer has a question about Start Up at Pre Bias condition.

I would be grateful if you could advise.

---

An external 3.3V is connected to the output of the TPS63031 via a 50kΩ resistor.

(1)Does it support pre-bias startups?

(2)If OK, current flows into the device from 3.3V through a resistor.

Is there a limitation on the inflowing current of output pin?

I appreciate your great help in advance.

Best regards,

Shinichi
