Description
LM2596S DC-DC Buck Converter Power Supply
DC-DC Buck Converter Step Down Module LM2596 Power Supply is a step-down(buck) switching regulator, capable of driving a 3-A load with excellent line and load regulation. These devices are available in fixed output voltages of 3.3 V, 5 V, 12 V, and an adjustable output version.The LM2596 series operates at a switching frequency of 150kHz, thus allowing smaller sized filter components than what would be required with lower frequency switching regulators.
This is an LM2596 DC-DC buck converter step-down power module with the high-precision potentiometer, capable of driving a load up to 3A with high efficiency, which can work with Freeduino UNO, other mainboards, and basic modules. When the output current keeps greater than 2.5A (or output power greater than 10W), please add a heat sink to it.
This device is internally compensated to minimize the number of external components to simplify the power supply design.
Since LM2596 converter is a switch-mode power supply, its efficiency is significantly higher in comparison with popular three-terminal linear regulators, especially with higher input voltages. The LM2596 operates at a switching frequency of 150 kHz thus allowing smaller sized filter components than what would be needed with lower frequency switching regulators.

Customer Reviews
Used it to step down 5v to 3.7v. Works great
I used one of these converters with output adjusted to 2.5vdc. It powers a triple exhaust fan for my car from 12vdc. It's so small it fits into the battery cavity replacing 2 AA batteries. Love it.
I used this to knock 24vdc down to 5vdc for a Raspberry Pi. It was easy and straight forward.
Bought it to wire 12v fan on my 24v 3d printer.Holes big enough for easy wire soldering, adjustment screw is solid, set it up for 12v using multimeter and it works flawlessly so far.Still have a second one unpacked for future projects.
Worked great
The product was exactly what I wanted and I am so happy with my purchase.
Inexpensive for what it is. Easy to adjust and put into service.
Simply solder in the line side, adjust the voltage on the output side, then solder on your output wires. Too easy!
These are working great for my projects. Easy enough to hook up. They are a little bulky. But if space is non issue I can't fault the unit.
It worked first time but when i charged second time It stopped working
