Power Supply DC-DC Buck and Boost Voltage Converter LM2577 5-25V to 0.5V-25V
LKR 1,290.00
Input and output voltage can display alternately
The starting state can be set freely.
This modlue has the function of controling the start-up and shutdown by the button. So it can control easily the state of output
This module have the big power MOS to protect the circuite in case of connecting reversely. This can improve the effiency and reliablity.
