Use Original Texas Instruments USA LM2596 Max 3.0 Ampere
High-power LED Adjustable CONSTANT CURRENT driver
Solar Panels and Wind turbines
For LED constant current driver usage:
Make sure operating current and Max operating Voltage of the LED you need to drive.
Adjust the constant voltage potentiometer to make sure the out put Voltage is up to LED Max operating Voltage.
(1,2,3,4 steps to connect the power module input and output load does not take LED.)
