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.
Input Voltage: DC 4~20V
Output Voltage: DC 0.8~17V Adjustable
Output Current: up to 2A
Buck Efficiency: email@example.comV, 87%@8V, 88%@13V, 84%@18V
Quiescent Current: 5mA@6.5V, 8mA@8V, 14mA@13V, 19mA@18V
