LM5041A: Can LM5041B be used as alternative

Hi Team,

My customer is currently using LM5041A in their design and are facing shortages. They are trying to use our LM5041B, but are facing issues in their testing. Below is their feedback:

For B every time when the module turn off, buck drive is low, the bus line has energy left. When next turn on comes quickly,

PUSH-PULL MOS will open with 50% duty to endure the bus energy discharge. This will result in the breakdown of PUSH-PULL MOSFet.

We found this failure at frequent on/off.

Is there anthing that can be done for them to use the B version instead?

Thanks!

BR,

Alfred
