Other Parts Discussed in Thread: UCD90120A

Hi,

I put a UCD90120A IC in the EVM.

As a default it configures one rail.

i wrote the Voltage I want to the hardware but in the Monitor window I see nothing. I think I have a basic problem I cannot see.

the EVM is connected to PC through a USB.

Can someone support?

Thanks.

Hi,

Are you using your EVM or is it the TI EVM? I can help you if you can provide me the config file(.xml) that you have setup. It should be some mistake in configuring the Vout scale monitor parameter or pin assignment.

Thanks, Spandana

I realised that your title stated that you are using a HPA650 EVM. This is an open loop board which doesn't have any power rails setup on the board.So the Monitor pin isn't monitoring any voltage. You would need to connect the Enable and Monitor lines with some actual power supplies to see the behavior of the device.

Thank you, I have mistaken with the older board.

Sorry!
