Original question:
LMR60440-Q1: Can TI provide the simulation model of the LMR60440?
Tool/software:
Hi All,
Is there a simulation model that can show the stability of the device?
-Jared
Hi Frank,
I can run it past the engineer. Can you please send over the model?
-Jared
Hello
See attached. You will need to use the include file for setting parameters.
Thanks

*GM2 variable modified on 7/1/2024 based on feedback from design. This value was back calcualted based on input from design
*Where design informed me that GM2 is 28% percent of HS peak command of 6.9A which is about 2A.
*with this new GM2 value, the actual GM2 will be represented by Imod in simplis.
*Note that the new GM2 value is not working proerly in simplis. Need to investigate further
*NEG_LIMIT will change for each different current trim
*NEG_LIMIT is 1.7A typical for 3A and 4A trims
*NEGLIMIt is 1A for the 2A current trim
