Hi team,
One of our customer is using LMC7660 and getting -1.5V for 4.5V input but the ckts works if replaced with TC77660. Schematic is ok and attached is same for reference. Can you plaese help with your comments on the same. Also can you please help with the Spice model of the same for quick simulation as we are not able to find the reason.
Thanks in advance for your support.
