CTM uses LM5145 as the DC48V to DC28V power supply, and the maximum output current is 8A.
We set the overcurrent protection point to 11.2A.
The test found that the overcurrent protection found that the hysteresis was large:
When the load is loaded to 15.8A, the overcurrent protection starts; when the load is reduced to 10.1A, the output voltage is restored.
Can the hysteresis be adjusted?
We use on-resistance of MOS, RDSON (Q2) mode
