DC-DC Step-Down With Display LM2596 4-40V With 3 LED Digit

The standard LM2596 buck converter with a three-digit LED display showing the output voltage directly, which removes the meter-and-guesswork step from setting it up. Particularly useful on a bench or in a panel where the voltage needs checking at a glance rather than probing with a multimeter. A button typically switches the display between input and output voltage. Built-in display removes the need for a multimeter; Set and verify output voltage at a glance; Display switches between input and output; Same proven LM2596 buck circuit
