LM5050-1: have leakage between Vs and Vout

Part Number: LM5050-1

Hi,

      I have a problem.I used LM5050-1 in a double battery system.But there is a 8V voltage on the vin when I just used the one battery.

I found this notice in the datasheet:

If Vs is powered while IN is floating or grounded, then about 0.5mA will leak from the Vs pin into the IC and about 3mA will leak from the OUT pin into the IC. From this leakage, about 50 uA will flow out of the IN pin and the rest will flow to ground. This does not affect long term reliability of the IC, but may influence circuit design. See Reverse Input Voltage Protection With IQ Reduction for details on how to avoid this leakage current.

Can I do something to prevent the leakage?

Best regards,

Teddy
