LED multi string linear constant current sink 01

LED multi string linear constant current sink 01 PUBLIC

DC Sweep doesn't simulate properly in CL for all values of R7. Time Domain simulation shows erroneous current spike at startup. See below.

LED multi string linear constant current sink 02

LED multi string linear constant current sink 02 PUBLIC

An attempt to get the time domain sim of: LED multi string linear constant current sink 01 to work properly. It doesn't. Time Domain simulation still shows erroneous current spikes at startup.

Damping vs. Time Step 03

Damping vs. Time Step 03 PUBLIC

Beware that, in CL, the damping in circuits including inductors is very dependent on the Time Step but is independent of Stop Time. This is with a Stop Time of 100u and a Time Step 100n.
