Adjustable XL6009E1 boost converter module for stepping a low-voltage DC rail up to a higher DC output. This compact board uses an XLSEMI XL6009E1 switching regulator with a multi-turn trimpot, screw-terminal-style input/output pads, and a large inductor for small electronics and printer accessory power experiments.
Why this over a fixed power supply
- Adjustable output: set the output with the onboard 25-turn potentiometer instead of being locked to one voltage.
- Boost-only behavior: useful when your output voltage needs to be higher than the input rail.
- Small module format: approximately 43 × 21 × 14 mm, so it fits easily in electronics bays and bench wiring setups.
Specifications
- Regulator IC: XLSEMI XL6009E1
- Converter type: non-isolated DC-DC step-up / boost
- Input voltage: 5–32 V DC
- Adjustable output: up to 35 V DC, output must be higher than input
- Switching frequency: 400 kHz
- Rated module output current: up to 4 A, depending on input voltage, output voltage, cooling, and load
- Adjustment: onboard multi-turn trimpot
Use cases
- Boosting a 5 V, 12 V, or 24 V DC rail for small electronics, LEDs, fans, sensors, and bench projects.
- Printer accessory experiments where a compact adjustable DC rail is more useful than a full enclosed supply.
- If you need a fixed main printer PSU instead of a boost module, see the Mean Well LRS-35-5 or the larger Mean Well LRS-350-24.
Gotchas
- This is not a buck converter: it will not step voltage down.
- Do not treat the headline current as continuous current at every voltage ratio. Higher boost ratios reduce usable output current and may require airflow or heatsinking.
- Set and verify the output voltage with a multimeter before connecting sensitive electronics.
