LM2587 DC-DC 3.5 - 30V Voltage Amplifier Module
The input voltage of the LM2587 voltage regulator should be 3.5V-30V and the output voltage should be 4.0V-30V. The maximum input current is 5A. The efficiency of the module is 92%.
When you test, if the output voltage is not higher than the input voltage, turn the potentiometer clockwise, the output voltage will rise. If you turn it counterclockwise, the module will be damaged due to high input voltage.
