I am using Texas Instrument's TINA simulation software. I want to do simulation of circuit i.e. that can be used as USB charging device for smartphones .It is a buck converter that converts 110Vdc into 5Vdc,2A. I have a schematic in which there is one opto-coupler (O1)named TCMT1100 not available in the TINA library. There is no TINA library file of TCMT1100 available on internet too. When I tried checking for alternate component ,it is also not available . Even there is not a single opto-coupler available in TINA library

So can anybody help me regarding this issue? enter image description here

TINA is a free tool supplied by Texas Instruments to help in designing products using TI parts. It is a TI business tool. The TCMT1100 is made by Vishay, and Vishay does have SPICE model for this part, so you can technically include this into TINA library as a subcircuit or other proper import method.

  • \$\begingroup\$ I have answered the question why TINA does not have models for optocouplers. To find answers about porting SPICE netlists into TINA, please go to TI TINA user groups. \$\endgroup\$
