*Note:

 D6 is for negative voltage clamping on V

OUT

 of DC2543B board in output overcurrent test with electronic load. Some electronic loads draw negative 

current in CC mode when evaluating the output overcurrent protection feature of DC2543B, which can violate the absolute maximum voltage rating –0.3V 

for V
