This is DC/DC step down regulator module, adjustable +1.8 to 36Vdc output voltage at maximum output current of 12A. 

Ideal for battery operated projects requiring a higher current regulated power supply.

  These modules use the high efficient XL4016 DC/DC converter IC, and applications include LED drivers, battery chargers and regulated variable power supply. This converter operated in buck topology, i.e.step down converter.

The input voltage must higher than output voltage.
