Note:

 It is recommended to set the electronic load in CR (constant resistance) mode for evaluation of 

the DC2543B board. Some electronic loads draw negative current in CC (constant current) mode when 

evaluating the output overcurrent protection feature of DC2543B, which can violate the absolute maximum 

voltage rating –0.3V for V
