Infineon EVAL_1ED020I12-BT EiceDRIVER Evaluation Board Application Note

Overview

This application note describes the EVAL_1ED020I12-BT evaluation board, designed to demonstrate the Infineon 1ED020I12-BT and 1ED020I12-FT EiceDRIVER high voltage gate driver ICs. The board features a half-bridge configuration driving two IKW25N120H3 IGBTs. Key technical features include galvanic isolation via coreless transformer technology, short circuit protection with VCEsat monitoring, undervoltage lockout (UVLO), and an active Miller clamp. It incorporates an isolated DC-DC converter for bipolar gate supply (+15V/-7V) and supports high voltage supplies up to 800V. The document provides detailed schematics, PCB layout information, and a complete bill of materials including components from Infineon, STMicroelectronics, and Nexperia.
