Hi,
I'm testing the onboard voltage control. I'm facing a very weird issue. I configured the EVM in buck mode with jumpers according to the user guide. It was working and the D12 yellow LED was also lit. I measured 12.5V across the 12V port, while applying a voltage of about 24V on the 48V port.
I switched everything off and restarted the setup without changing anything, and now it doesn't work. D12 doesn't turn on, and there is no voltage on the 12V port. I literally did not change anything and the jumper setting and wire connections are exactly the same. It seems like the chip suddenly is not getting power. The jumper settings are shown in the picture below:
Is there something I'm missing and could you please help me if possible?
