1 Introduction

The 2ED250E12-F evaluation driver board shown in Fig. 1 was developed to support customers during their

first design steps with the 1200V PrimePACK™ IGBT module. The evaluation driver board is a fully

functional IGBT module driver where two 1ED020I12-F driver IC process control and feedback signals and

provide galvanic insulation. An embedded isolated DC/DC converter supplies gate drive power to both IGBTs

of a halbridge configuration.

The 2ED250E12-F Evaluation driver boards are available from Infineon in small quantities. Functions and

properties of these parts 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 his specific requirements.

The design of the 2ED250E12-F was performed with respect to the environmental conditions described as

design target in this document. The requirements for leadfree reflow soldering have been considered when

components were selected. The design was tested as described in this documentation but not qualified

regarding manufacturing and operation in the whole operating ambient temperature range or lifetime.

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.
