Part Number:LM5175
The LM5175PWPT is destroyed during power up of the input voltage. For the input voltage I use an laboratory power supply with current limitation. Because of a large inrush current, the current limitation of the laboratory power supply gets active during power up. As result the internal linear voltage regulator for VCC (7.35 V) of the LM5175PWPT is destroyed. After replacement of the LM5175PWPT the power supply board is operational again. The power supply board creates 15 V output voltage out of 24 V input voltage.
Is such an error known with the LM5175PWPT?
