Summary

DC Sweep doesn't simulate properly in CL for all values of R7.

Time Domain simulation shows erroneous current spike at startup.

See below.


Description

There's an LTspiceIV file:

LED_multi_string_linear_constant_current_sink_01.asc

and associated plot file:

LED_multi_string_linear_constant_current_sink_01.plt

in here:

LED_multi_string_linear_constant_current_sink_01.7z

which you can download from:

https://drive.google.com/folderview?id=0B2wonnsWWfTXOTVmNDU2Y2MtYzJlZi00M2MyLWExZDAtM2JhY2NiNGI4ODBi&usp=sharing

and you'll need to download and install the free LTspiceIV simulator from:

It just works.
