Other Parts Discussed in Thread: TINA-TI,
Tool/software: TINA-TI or Spice Models
When I use the TINA-TI model from SpiceRack it does not give me all the pins that are available on the IC?

Hi Herman,
Is there a Spice model with full functionality? The one that is available for TINA-TI is for SEPIC topology. I want to use it for boost/flyback.
Here's what I found from the netlist file:
*****************************************************************************

** Released by: WEBENCH Design Center, Texas Instruments Inc.
* Part: LM3478
* Date: 13APR2017

* EVM Order Number: AN-1990
* EVM Users Guide: SNVA405A–January 2010–Revised April 2013
* Datasheet: SNVS085W -JULY 2000-REVISED DECEMBER 2014

*****************************************************************************
* Model Usage Notes
*
* 1. Since this is an average model used for AC analysis, only the pins affecting AC analysis
* are modeled.
*
* 2. Make sure the value of inductors(L1 and L2),frequency adjusting resistor(RFADJ), RSL , and RSN used in
* the testbench is passed to the macromodel appropriately. The macromodel uses these values internally.

Hi Ziad,
The TINA reference design is not available for Boost average model configuration. You can create that design in TINA as unencrypted average model is available on website. It contains both boost and sepic average model.
LM3478 Unencrypted PSpice Average Model
You can create MACRO of LM3478 boost average model in TINA-TI from unencrypted Lib file & configure test bench similar to released Pspice model (as shown below).
Please let me know if you have any questions.
