Tool/software:
Hi E2E
Currently using UCC28951 to test dcdc products, the vds that output sr during startup will have abnormal spikes, causing the sr mos to burn out.
I have tried voltage and current modes so far, and RTmin/DELAB/CD have also been adjusted. If it is still troublesome, please help me find out how to solve it.
The picture below is the schematic and wavefroms
Vin-185~410Vdc
Output:48V/32A
Start up 2nd Vds
