Part Number:LM25066
Hello I have LM25066EVK. The shunt was changed to 10mOhm ( stock 0,5mOhm) to gest 2.5A current limit at Vref 25mV. Configuration of the board is as follow: CL to GND, CB to GND, RT to GND.
Vin 12V from DC power supply limited to 5A and I perform hard short circuit on the output.
What I see is that during limitation time current is limited to about 0,5A not to 2.5A. Why is it so I enclose screen? First peak is about 3.5Amps. why there is such peak?. Pink is current 0.5A/div Yellow is the gate voltage refered to the Vout.
