Frequently Asked Questions
Q: Can this DC-DC boost converter module step down voltage as well?
A: No — this is a step-up (boost) converter only. It is designed to increase the output voltage above the input voltage. The output voltage must always be set higher than the input voltage for proper boost operation. It cannot be used as a buck (step-down) converter.
Q: What is the maximum load I can connect to this 100W boost power supply module?
A: The module supports up to 100W of output power with a peak input current of 10A and a recommended continuous input current of 6A. For sustained use, it is best practice to operate at or below the continuous current rating to ensure long-term reliability and prevent overheating.
Q: How do I adjust the output voltage on this adjustable power supply board?
A: The output voltage is adjusted using the onboard potentiometer (trim pot). Use a small screwdriver to turn the potentiometer while monitoring the red LED voltmeter display, which shows the current output voltage in real time. Always verify the output voltage with a multimeter before connecting sensitive loads.
Q: Is this power supply module suitable for charging lithium batteries?
A: This module can provide an adjustable boosted DC voltage that may be used in battery charging circuits, provided you set the output voltage correctly and use appropriate protection circuitry. It does not include built-in overcharge protection, so always ensure you are using suitable charge management components in your circuit design.
