About this document

The purpose of this board is to enable the evaluation of the FF6MR20KM1H, FF4MR20KM1H and FF3MR20KM1H
CoolSiC™ MOSFET modules. The evaluation board allows users to evaluate the device performance via double-
pulse measurements.
Scope and purpose
The properties of this board are described in the design features' chapter of this document. The remaining
sections provide information to enable designers to copy, modify and qualify the design for production,
according to the customer-specific requirements.
Environmental regulations have been considered in the design of the EVAL-FFXMR20KM1HDR board.
Components qualified for a lead-free, reflow soldering process have been selected. The design has been tested
as described in this document, but not qualified regarding manufacturing and operation over the whole
operating temperature range or lifetime.
Intended audience
This document is intended for engineers who want to document and evaluate the switching performance of
Infineon CoolSiC™ 62 mm 2kV modules.
Evaluation board
This board will be used during design-in, for evaluation and measurement of characteristics, and proof of data
sheet specifications.
Note:
PCB and auxiliary circuits are NOT optimized for final customer design.

    The evaluation board at a glance Main features The EVAL-FFXMR20KM1HDR is an evaluation board for the EiceDRIVER™ 1ED38x0Mc12M gate drivers ICs to be used together with our 62 mm 2 kV half-bridge module with CoolSiC™ MOSFET. The board is designed for easy measurement and configuration of the gate driver and module parameters.
  • Page 8: Typical Applications

    The EVAL-FFXMR20KM1HDR operates with a supply voltage of up to 24 V. It generates an output voltage of up to 18 V at the gate terminals, depending on the load conditions. To switch the device, a pulse width modulation (PWM) for both, the top and the bottom side need to be applied at the connector input.
