LM2596 LM2596S DC-DC Step-Down Power Supply Module The LM2596S Adjustable DC-DC Step Down Module can step-down the input voltage to a range of 1.25 – 35V at up to 2A

Features:

•  DC to DC step down module
• Thickened circuit boards
•  Advanced solid-state capacitor
•  Short circuit and over-temperature protection

Instructions:
1. Power (3-40V), power indicator light, the module is working properly.
2. Adjust the blue potentiometer knob (clockwise rotation generally boost,counter-clockwise rotationTurn down) and reach with a multimeter to monitor the output voltage required voltage.

Note:
Current work long hours is recommended for use in less than 2.5A, while adding bulkHeat sink (10W output above),because it is the step-down module, in order to ensure stable output Set,please keep the minimum 1.5V differential.

Input voltage range: DC 3.2V to 40V (input voltage must be higher than the output voltage above 1.5V. Could not boost)

Output voltage range: DC voltage from 1.25V to 35V continuously adjustable, high efficiency (92%) of the maximum output current of 3A.

The measured 12V input, 5V output current is 1A load regulation of less than 1%
