AMC1100: Output is faulty when power on

Part Number: AMC1100

Hi,

Our customer is using AMC1100. When power on, the output voltage is abnormal occasionally. Sometimes the output voltage is bigger than normal and sometimes the output voltage is smaller than normal. The abnormal state will continue until switching off the chip.

So here are some questions:

1. What condition will cause this issue?

2. How to avoid this issue?

Thanks.
