LM2596S buck module

The LM2596 series of regulators are monolithic integrated circuits that provide all the active functions for a step-down (buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation.

This unit can step down input voltages of 32V to a minimum of 1.5V with minimum heat dissipation over the regulator itself. Voltage can be adjusted by means of the trim-pod on the module itself, and fine-tuning of the voltage can be done while the unit is in use.

Note:
Please ensure you use a heat sink when you are exceeding the current limit of 3A.

Please note that the trim pot that is used to adjust the output of the module needs to be turned quite a few times before you can see a change in the output.
