LM5176: LM5176 peak load

Hsu cheng
Expert 1565 points
Part Number: LM5176

My customer specifications are as follows: If the OCP is set at 4.5A, the pin of this IC can reach the following peak load and ocp function. If the setting is not possible, is there any other way to do it!

    Hi Hsu cheng,

    If by OCP you mean the average output current limit, then you will need to delay the ISNS signal by using a large capacitor (in uF scale) across ISNS(+) and ISNS(-). However, you current sense resistor from the low side MOSFETs sources to GND should be selected to allow your 21A load to pass, namely the cycle by cycle current limit should be higher than delivering the 21A.


    Thanks
