Part Number: AMC1100
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?
In reply to Tom Hendrick:
Thank you for your reply.
The power is OK and the schematic refers to the datasheet. I attach the input, output_normal and output_abnormal waveforms. Please review them. By the way, this issue occurs occasionally and after power-up again, it disappears.
In reply to Kevin Xiong:
Is it just one AMC1100 behaving this way or multiple devices? Can you get us the lot trace code from the topside of the package?
Hi Kevin, I sent you an e-mail to your my.ti account, lets work this off line for the moment. I'm closing this thread for the moment and will update with any pertinent detail that comes up.
