DC-DC Converter FAQ

What is the difference between a Buck and a Boost converter? +

A Buck converter (Step-down) reduces the input voltage to a lower output voltage.
A Boost converter (Step-up) increases the input voltage to a higher output voltage.

What does "Isolated" vs "Non-Isolated" mean? +

Isolated converters have electrical separation (via a transformer) between input and output, which provides safety and noise immunity.
Non-Isolated converters share a common ground and are typically more efficient and compact.

What is the efficiency of this converter? +

Efficiency is the ratio of output power to input power. High-efficiency converters (e.g., >95%) minimize power loss as heat, which is crucial for battery-powered applications and thermal management.

Why is my converter overheating? +

Possible causes:

Exceeding the rated output load → Reduce power draw.
Poor ventilation → Ensure airflow around the unit.
Faulty wiring → Check connections.

The output voltage is unstable. What should I do? +

Try:

Check input voltage (must be in input voltage range).
Verify load is within output limit.
Test with a multimeter to confirm output.

Can I use this with solar panels? +

Yes, DC-DC converters are commonly used in solar systems to match the panel voltage to the battery or load voltage. Ensure the input voltage range covers your solar panel's maximum power point (MPP).
