Overview

This document provides a comprehensive technical overview and feature description for the EVAL_7126G_100V_GaNc evaluation board. The board is designed to evaluate the IGC033S10S1 100 V CoolGaN power transistor and the 1EDN7126G EiceDRIVER TDI gate driver in a half-bridge topology. It supports DC-DC conversion, such as buck or boost modes, and motor drive applications. The guide includes detailed specifications, test setups for double-pulse testing, on-board dead-time generation, and thermal management options. It also provides a reference PCB layout, schematic, bill of materials, and experimental results for efficiency and switching performance under varying conditions.
