EVAL-1ED020I12F2-DB user guide 

Isolated driver daughter board to evaluate 1200 V CoolSiC™ MOSFET 

About this document 

Scope and purpose 

This user guide explains how to operate the evaluation board “EVAL-1ED020I12F2-DB” (daughterboard) 
together with the “Evaluation platform 1200V CoolSiC™ MOSFET in TO247 3pin / 4pin Rev. 2.” (motherboard)  

 

Intended audience 

This document is intended for owners and users of the evaluation board. 

 

Evaluation Board 

This board is to be used during design-in tasks, for evaluation and measurement of product characteristics, and 
proof of data sheet specifications.  

Note:

 

PCB and auxiliary circuits are NOT optimized for final customer design.
