Frequently Asked Questions (FAQ)

Q1: Is this module a step-up or step-down converter?
A: This is a step-down (buck) converter only. The input voltage must always be higher than the output voltage.

Q2: Can it really deliver 5A continuously?
A: Yes, it can deliver up to 5A with adequate cooling. However, for long-term continuous use, 4A is recommended to ensure thermal stability.

Q3: Can I use it as a battery charger?
A: Yes. Because it supports constant current and constant voltage, it is suitable for DIY battery charging circuits when configured correctly.

Q4: Does it include over-current protection?
A: Yes, the XL4015 IC provides built-in over-current and thermal protection for safer operation.

Q5: Is this suitable for laboratory and educational use?
A: Absolutely. It is widely used in labs, training institutes, and R&D environments due to its stability and adjustability.
