Mini Adjustable 2A Buck DC/DC Converter Module (DC 4-20V Step-Down)

Description

This is a buck (step-down) DC/DC converter with very small dimension (20 x 11 x 5 mm).

The output voltage can be adjusted via the potentiometer on board, or you can cut the “ADJ” trace on the back and joint the pads for a fixed voltage. The example below shows how to make the board output fixed 5V.
