20W Adjustable DC-DC Buck Converter with Digital Display

OverviewThis is a 20W adjustable DC-DC buck converter module with a digital display. It is based on LM2596 3A step-down voltage regulator and supports input of 0 ~ 40VDC with an accuracy of ±0.05V. On a regular buck converter, there is no display and you must measure the output manually with a multimeter, which can be slow and inefficient. This buck converter has a display with the output voltage readout integrated right into the board. You can change the output by adjusting a screw potentiometer that is also integrated into the board. This module can be used in DC applications such as batteries, power transformers, DIY adjustable power supplies, 24V vehicle power supplies, industrial equipment, 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V, 36V to 24V.
