Its compact footprint and simple adjustment make it a practical upgrade over older modules such as LM2596 for higher-current needs.
Installation and Tuning Tips
- Always connect a suitable input supply rated above the expected load and within 8V to 40V.
- Use a stable multimeter to set the output voltage before connecting sensitive loads.
- Mount the module where the heat sink can ventilate freely. Add forced airflow for continuous high-current operation.
- Keep wiring short and use appropriately sized connectors and wires to minimize voltage drop.
Safety and Best Practices
- Observe correct polarity on input and output terminals to prevent damage.
- Do not exceed the maximum current rating without additional cooling or protection.
- When charging batteries, ensure correct charge profiles and implement proper battery protection circuits.
- Isolate the module from conductive surfaces during testing to avoid short circuits.
