The LM2596 Adjustable DC-DC Step-Down Converter Module with LED Display is a compact buck regulator built around the LM2596 switching IC, with a built-in 3-digit LED voltmeter that shows the output voltage in real time. A screw-adjustable trimmer sets the output level, making it a handy drop-in supply for powering 3.3V, 5V and 12V circuits from a higher-voltage source.
Key features:
- LM2596 Regulator: A proven switching buck converter IC operating at a 150 kHz switching frequency.
- Adjustable Output: Onboard trimmer sets the output from 1.25V up to 37V to suit different projects.
- Built-In Voltmeter: A 3-digit LED display continuously shows the output voltage without a separate meter.
- Wide Input Range: Accepts an input voltage from 4V to 40V DC.
- Screw Terminals: Input and output screw terminals allow fast, tool-free wiring.
- Compact Size: A small footprint fits easily into enclosures and battery-powered projects.
It is well suited for powering microcontroller boards, LED strips and other electronics from batteries, solar panels or unregulated DC supplies.
