Hi, I was designing dc-dc converter using LM5030 , the output specifications are
Output 1: 13V, 4.9A
Output 2: 13V, 3.8 A
the primary input voltage is 74V and the estimated primary continuous current is 4.3A
so for overcurrent protection is was going to set the current sense resistor connected to current sense pin to stop the ic for current above 5 A on the primary side
The issue is as per the simulation the inrush current on the output capacitor was 22 A so the corresponding increase in current demand would be reflected on the primary side which would exceed the set current limit hence would stop the ic and hence the converter wouldn't work at all
Any solution to this?
