LM2596 DC-DC Buck Converter Adjustable Step Down Power Supply Module

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.
