Requiring a minimum number of external components, the LM2577 3A DC-DC Step UP LED Voltmeter is a 150 KHz fixed frequency PWM buck (step-down) DC/DC module. It is cost-effective and simple to use. The integrated digital voltage meter and high precision multi-turn potentiometer allow for easy setting of any desired output voltage within the supply range without the need for an external voltage meter. The module has a wide operating range with a DC input supply range of 3-34V and an adjustable output range of 4-35V.
When adjusting the blue potentiometer, it is recommended to use a multimeter to monitor the voltage. Rotating clockwise raises the voltage, while rotating counterclockwise lowers it. If the module output voltage cannot be adjusted (always equal to the input voltage), adjust the potentiometer counterclockwise 20 laps or more until it works.
