Project name:

DC - DC adjustable step-down module Based on the LM2596 chip


Input: PCB diagram + for input IN the anode, the IN - for input cathode, to 40v dc 5v input voltage, input voltage must be higher than to the output voltage of 1.5v above. Can't booster)

Output: PCB figure out + for the output of the anode, the out - for negative dc 5v to 35v output voltage adjustable, high efficiency maximum output current is 3A.

Normal continuous working current should be kept within the 2.5 A, make the modules work steadily.
