Part Number: TPS61099
Dear TI engineer,
I'm testing the board uses TPS610993 to boost from alkaline battery voltage to 3.0V.
I found an unexpected high voltage in load variation test. I think TPS610993 is fixed output (3.0V).
What is happening in my board?
I tested same test with TPS61099EVA-023. No high voltage. 3.6V fixed type is mounted in TPS61099EVA-023 .

Thank you for you quick response.
>1. is this behavior found in several boards？
I tested 2 boards. I found this behavior in both.
>2. could you make sure if you are using TPS610993, not TPS61099?
