Hello,
I am using the LMZ14203HTZ/NOPB DC-DC converter to get 7.5V output with maximum current output of 3A from an input voltage range of 19.8V to 25.2V.
I got the circuit from the WEBENCH designer. The details of the circuit can be found at the following link. I attached a PDF copy with all the details also. Kindly check for reference.
I need to include this circuit in my overall design and check the design performance. So, I was making the circuit in the PSPICE for TI software. The schematic file can be found in the following link. I have attached a PDF copy of the schematic. Kindly check for reference.
Unfortunately, I am not getting 7.5V output from the output PIN in the PSPICE design. I have attached the plots of the input and output voltage. Please check.
Can anyone suggest what the issue could be?
Thanks,
Subhadeep
