Description
DC-DC step-down power supply module input: DC3.2v-35v (input voltage must be 1.5 V higher than the output voltage, no boost)
DC-DC step-down power supply module output: DC1.25v-30v voltage is continuously adjustable, maximum output current is 3 A
LM2596 is a buck module, the input voltage must be higher than the output voltage and cannot boost.
If the output current is greater than 2.5A or the output power exceeds 10W, please enhance heat dissipation when working for a long time.
Note: Before using it for the first time, when the module is de-energized and not connected to a load, turn the copper-headed adjustment cap of the blue potentiometer (aim it at your chest) counterclockwise to the end (more than 30 turns). Hear There is a “click” sound, and finally power on, use a multimeter to monitor the module output voltage, and turn the potentiometer clockwise to reach the ideal voltage
