　　The gate driver evaluation board EVAL_1ED020I12-B2 was developed to show the functionalities and key features of the Infineon IGBT gate driver 1ED020I12-B2 (applied also to 1ED020I12-F2).

　　The board is available from Infineon in sampling quantities. The properties of this part are described in the datasheet chapter of this document, whereas the remaining paragraphs provide information intended to enable the customer to copy, modify and qualify the design for production, according to their own specific requirements.

　　The design of the EVAL_1ED020I12-B2 was performed with respect to the environmental conditions described in this document. The design was tested as described in this document, but not qualified regarding manufacturing, lifetime or over the full ambient operating conditions.

　　The boards provided by Infineon are subjected to functional testing only.

　　Due to their purpose Evaluation Boards are not subjected to the same procedures regarding Returned Material Analysis (RMA), Process Change Notification (PCN) and Product Discontinuation (PD) as regular products. These Evaluation Boards are used for development support only and should not be used as reference design for volume production.
