I wrote about how to add elements to the schematic in LTSpice in this article: http://sigaris-electronics.eu/2018/11/ltspice-adding-an-element-model-to-the-schema/ . In this post I will describe how to add an element in Tina-TI from the official model from Texas Instruments.
For simplicity, Texas Instruments has prepared a tool that simplifies the design process of power inverters. This tool is called the Power Stage Designer Tool. At the time of writing this post, this tool was published in version 4.0.
