When I connect it to the daisy chain of other boards, it suddenly will no longer power on, despite ~54V being passed through correctly to downstream boards.\n \n This is a real head-scratcher for me, and I’m having trouble making sense of it.

Input is up to 60V DC, board converts to 5V and then down to 3.3V.\n \n The top board works correctly all the time. But the bottom board has strange issues. Everything works perfectly when I connect it to my bench power supply at 53V. The board powers up with no problems. When I connect it to the daisy chain of other boards, it suddenly will no longer power on, despite ~54V being passed through correctly to downstream boards.\n \n This is a real head-scratcher for me, and I’m having trouble making sense of it. I’m not so much looking for The Solution as to what steps I should take to troubleshoot this.

Everything works perfectly when I connect it to my bench power supply at 53V. The board powers up with no problems. When I connect it to the daisy chain of other boards, it suddenly will no longer power on, despite ~54V being passed through correctly to downstream boards.\n \n This is a real head-scratcher for me, and I’m having trouble making sense of it.

Input is up to 60V DC, board converts to 5V and then down to 3.3V.\n \n The top board works correctly all the time. But the bottom board has strange issues. Everything works perfectly when I connect it to my bench power supply at 53V. The board powers up with no problems. When I connect it to the daisy chain of other boards, it suddenly will no longer power on, despite ~54V being passed through correctly to downstream boards.\n \n This is a real head-scratcher for me, and I’m having trouble making sense of it. I’m not so much looking for The Solution as to what steps I should take to troubleshoot this.
