TPS54340-Q1: start up and stop volatge calculation issue as per datasheet

Part Number: TPS54340-Q1

Hi,

Im trying to use the below equation for Vstart and Vstop voltage calculation.

But its not matched with the actual value arrived.As per the above equation,If Vstart=5.75V and Vstop =4.5V.

Ihys=3.4uA. then RUVLO1 value should be as 442K .

Am I missing anything in my calculation.

Pls let me know.

Thanks-Arumugam
