2A Voltage Buck Converter Module (LM2596), Fixed Output Voltage (3.3V/5V/12Vdc) or Adjustable Output

This is an adjustable voltage buck converter with LM2596-ADJ, generally used to step-down dc-dc voltages. The voltage buck converter is a small and easy to use module with a fixed output voltage (3.3V/5V/12Vdc) or an adjustable voltage conversion range. 2 options are available, (1) Adjustable without display (2) Adjustable with 7-Seg Display.

Working of LM2596 Voltage Buck Converter Module

This is a DC/DC step-down voltage regulator that converts a wide range of input voltages (up to 40Vdc) into a smaller voltage between 1.5V and 35V, capable of driving a maximum of 3A load with excellent line and load regulation. This module can accelerate prototyping, because you can get the voltage you need (such as 3.3V, 5V and 9V) as easy as blinking eyes.

• The module converts input voltages by using the internal switching circuit to regulate an output voltage.
• (1) The module has a fixed Output Voltage (3.3V/5V/12Vdc).
• (2)The desired output voltage is adjustable by the onboard potentiometer.
• 2A / 3A fuse is strongly recommended to act as a protection component for the module.
• Please note that the input voltage must be larger than the output voltage.
