The customer face the output overvoltage issue of Enpirion EN2340. He said that the input and output were shorted and the load device was taken damage by the high voltage due to without the output overvoltage protection of EN2340.
So I'll propose LTM4622 and LTM4626 to the customer but I'm not sure that they have the output overvoltage protection. Regarding my experience, when the higher voltage hit on the output, VFB reach the higher voltage beyond the threshold level of OVP and the switching will stop. But I don't recognize only reading their data sheet.
