DROK LM2596 DC-DC Buck Converter

Product parameters:

Input Voltage: DC 4~40V(the input voltage should be higher than output voltage at least 1V)

Output Voltage: DC 1.25~37V(continuously adjustable)

Output Current: 2A(for stable operation), 3A max.

Voltmeter: 0~40V

Voltmeter Accuracy: .+/-0.1V

Internal Oscillation Frequency: 150KHz

There is a large area of copper on its back to enhance heat dissipation

Keep pressing the button for 1 to 4 seconds, display would be shut off

Calibration of input/output voltage

(1) Output voltage calibration

Firstly, press the button so that "OUT" LED lighted, the voltmeter shows the value of output

voltage; Keep pressing button for more than 2 seconds, then release.

display and "OUT" LED flashes simultaneously. That means enter output voltage calibration

mode.

Secondly, short press the button (normal speed), the voltage value is changed. The minimum

voltage display to 0.1V.

Thirdly, press the button for more than 2 seconds, release, to exit the output voltage calibration

mode. All parameters are save.

(2) Input voltage calibration

Firstly, short press the button so that "IN" LED lighted, the voltmeter shows the value of input

voltage; Keep pressing the button for more than 2 seconds, then release. Display and "IN"
