TPS61030: What does the part behave when the condition of Vin > Vout?

Part Number: TPS61030

Hi Team

Would you advise that is it possible to use with Vin > Vout condition even TPS61030 is a boost converter?

My customer will design not to meet the above conditions, but she wants to know what will happen if the above events occur.

As long as the customer confirmed it on the actual machine, it was operating at SW duty 100%.

Thanks

Best regards,

Shidara
