Other Parts Discussed in Thread: LM5145
Tool/software:
Hi !
This is Venu Gopal.
I have designed a DC-DC converter by using LM5145-Q1 buck switching regulator IC. I have designed it for an output of 24V and 20A output current. I have set a current limit of 30A by using the ILIM pin of LM5145 by connecting a resistor with value of 1.69Kohm. Now while I am performing my load tests output voltage is not regulating by LM5145 IC. Voltage is dropping to 14V, 16V and 18V when I am trying to draw current of more than 7A. What are the reasons for this voltage drop and what are the modification I need to do to my circuit? I am attaching Schematics below for the reference.
Thanks in Advance
