FAQ

Q1: How can I check if the converter is working properly?

Use a multimeter to verify the output voltage under load. A stable voltage indicates proper operation.

Q2: Can I power multiple devices from one converter?

Yes, as long as the total current draw is within the converter’s rated output current.

Q3: Why is the DC step down converter getting warm?

Heat is normal under moderate to high loads. Ensure there is airflow or a heatsink if operating near max rated current.
