DC/DC converter with adjustable 1.5-35V output

Step-Down DC/DC switching converter, with particularly small dimensions (48.35 x 23.35 x 14 mm), capable of converting a DC voltage between 3 and 40 volts into an output voltage from 1.5 to 35 volts (adjustable via trimmer). The maximum available current is about 3 A. The input voltage must exceed the output voltage by at least 2 volts.
