I want to ask if the reason is that the input power supply current is too small.

Due to the laboratory equipment, I provided the board with a 36V current limiting point of 1A, but the board has no output, and the D13LED light is not on. I want to ask if the reason is that the input power supply current is too small.

（My board is UCD3138HSFBEVM-029）

Hi
此时你带多大负载？
建议你按照使用指南操作顺序调试看看。

No electronic load. Because the experimental equipment can provide 3A current at most, and the input power is far less than 400W required by the operation manual, I want to ask whether the board can not be started due to insufficient input power, so there is no output.
