For safe handling and best practices when working with low-voltage electronics, refer to the OSHA Electrical Safety Guidelines.
Frequently Asked Questions
Q: Can this DC-DC converter module be used as both a boost and buck converter?
A: Yes! This module supports both step-up (boost) and step-down (buck) conversion. It accepts an input of 5.5V–35V DC and outputs a precisely adjustable 1.22V–16V DC, making it suitable for a wide range of voltage regulation tasks.
Q: What is the maximum output current this power supply module can handle?
A: The positive terminal supports a maximum output current of 3A, and the negative terminal supports up to 2A. Keep in mind that as output voltage increases, the available output current decreases — at 16V output, expect approximately 1A on the positive end and 0.7A on the negative end.
Q: How do I adjust the output voltage on this module?
A: The output voltage is adjusted using the onboard potentiometer dial. Turn it clockwise to increase the output voltage and counterclockwise to decrease it. The output can be precisely set anywhere within the 1.22V to 16V range.
Q: What input voltage do I need to power this DC-DC converter module?
A: The module accepts DC input between 5.5V and 35V. When using it in step-down (buck) mode, your input voltage must be at least 2V higher than your desired output voltage to ensure proper regulation.
