APPLICATION NOTE
Using the Demoboard for the TD350 Advanced IGBT Driver
1 Introduction
TD350 is an advanced IGBT/MOSFET driver with integrated control and protection functions. Principles
of operation and application examples for the TD350 are described extensively in application note
AN1944. The present application note concerns the characteristics and use of the demoboard available
for testing the TD350.

2 Printed circuit board presentation
The demoboard is a 26x35mm double-sided PCB with the TD350 and its peripheral components
mounted in a typical configuration (pictured in Figure 2). To aid in the understanding and easy
modification of the board, the PCB top-side and bottom-side layers, as well as the silk-screen previews
are shown in Figure 3.
The demoboard electrical schematic is presented on Figure 4, and the associated bill of material can be
found on Table 1 on page 5.
Let’s study step by step the demoboard original configuration, and the way it can be modified to be
adapted to the application.
