Small 2.5A step-down regulator module (LM2596-based)
A 45x20mm module which uses the LM2596 buck regulator IC. Input is 3.2-35V, output is 1.25-35V at up to 2.5A continuous.
Efficiency up to 92%. Output voltage is adjusted using a multi-turn trimpot. The input and output DC connections are made via pads in the corner of the PCB.
Note that as with a typical buck regulator, the output voltage must be at least a couple of volts lower than the input voltage for proper regulation.
