When I run .tran .5m startup for the LTM4622 the simulation runs properly , but I get the error shown below. I'm wondering whether I should worry about it, since the simulation results line up with the datasheet.

LTM4622 test module error log

I tried adding a capacitor to match the datasheet, grounding everything, and playing around with the simulation control settings, but I still get the same error.

I came across this error in a larger simulation with multiple LTM4622 and even though they each operated at different voltages/currents and had different attached circuitry, they all threw the same error. The order was slightly different though:

  1. u1:13-25
  2. u2:13-25
  3. u1:13-25
  4. u2:13-25

As for control settings, I ran the sim with defaults, and then tried:

  • Setting solver to alternate
  • Skipping the initial operating point solution
  • \$\begingroup\$ That's no error, it's just LTspice telling you that there is no current into that/those pin/s. It's pronted out in the error log because it's a log, for more than errors. Safe to ignore. \$\endgroup\$ – a concerned citizen Aug 5 '18 at 7:01
