TINA/Spice/TPS92515: Please help to identify the part "IC=0" and "IC-5" in circle in the schematics

Part Number: TPS92515
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hi, there,

I downloaded the PSpice model for the TPS92515 and it ran fine in the OrCAD PSpice simulation. There are something in the schematics that I need to know what that is and if its needed for our system to drive the LEDs. Please see attachment for the screen capture and I circle the items in questions, "IC=0" and "IC=5", what kind of device or component is that? are they just PSpice model? Where should I go to find them in the "Place" part drop down list? what is their function?

Thanks,

Terri

Hello Terry,

Those are not needed in a real circuit. Those aren't actually integrated circuits, I know it's kind of misleading, they are actually initial conditions. That is just a pspice thing to help the simulation go faster and converge easier. They just set Voff at 0V and Vcc at 5V to start the simulation and speed it up.

Regards,

Clint
