Frequently Asked Questions

Q: What is the difference between boost and buck modes on the XY-UDP converter?

A: In buck (step-down) mode, the module reduces the input voltage to a lower output voltage — for example, converting 12V input to 5V output. In boost (step-up) mode, it increases the input voltage to a higher output — for example, converting 5V USB input to 12V output. The XY-UDP automatically handles both scenarios within its rated ranges, making it a flexible all-in-one DC-DC power supply module.

Q: Can I use this module to charge lithium batteries?

A: Yes. The CC/CV (Constant Current / Constant Voltage) functionality makes this module well-suited for charging single-cell or multi-cell lithium batteries, provided you set the correct voltage and current limits for your specific battery chemistry and capacity. Always verify the correct charge parameters before connecting any battery.

Q: What input source can I use with the XY-UDP module?

A: The module accepts any DC source between 3.5V and 15V through its USB input connector. This includes USB power banks, USB wall adapters (with appropriate output voltage), or regulated bench power supplies. Ensure your input source can supply adequate current to support your desired output power (up to 15W).

Q: How precise is the voltage and current output?

A: The XY-UDP offers a voltage resolution of 0.01V with ±0.3% accuracy (+1 digit) and a current resolution of 0.001A with ±0.5% accuracy (+3 digits). This level of precision is suitable for powering and testing sensitive electronic components and circuits.
