We have used LTM4601 in our design for different voltage conversions. Recently we are facing issues with the newly assembled boards as these chips are not generating output voltages. We tried to identify the issue from different angles. First, we suspected the Assembling and tried assembling on another card, but the issue continued. Is there any way we can identify if the chips are faulty? Kindly share with us if there is any debugging procedure.
We purchased these components from Digikey. We never faced any problem with these ICs in the past on the same PCB.
