I would like to simulate a 5V and 7V supply each using an LMR62421. The input voltage will range from 3.7V to 5.0V. Each supply is designed to drive 0.15A.
When I attach the LMR62421X_trans model to the part in the simulation, I get the following error:
It looks like the error is pointing to the .SUBCKT NationalFET2A 10 20 30, where I noticed the following lines seemed to have a discrepancy:
.MODEL DMOS NMOS(LEVEL=3 VMAX=52.1k THETA=58.1m ETA=2.00m VTO=3.10 KP=10.69
.MODEL DCGD D (CJO=59.0p VJ=0.600 M=0.680
.MODEL DSUB D (IS=10.4n N=1.50 RS=0.100 BV=25.0 CJO=217p VJ=0.800 M=0.420 TT=86n
.MODEL DLIM D (IS=100U)
.ENDS
Also, between the end of the NationalFET2A subckt and the next subckt definition, there is a free standing .MODEL statement:
.MODEL myD30880 D BV=500 CJO=470E-12 EG=0.69 IBV=1E-6 IS=9E-6
+ M=0.8 N=1.442 RS=60E-3 VJ=1 XTI=2
*$
Is this correct?
What can I do to fix this problem?
Thanks, MK
