XL6009E1 Step-Up Adjustable DC-DC Switching Boost Converter
Couldn't load pickup availability
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.

Shipping:
US Shipping is via UPS or USPS. The way it is set up shows the least expensive options for standard, priority and express shipping. I can not take special requests for specific carriers at this time.
International shipping is mostly UPS, as I utilize Zonos/UPS integration to tally extremely accurate import and shipping costs.
I require a telephone and email with international orders and you must make yourself available to the carrier or your customs, should they require more information. If you are unreachable and the package is discarded or rerturned, I will not be responsible for rerturning your shipping cost.
If there is a problem with an international order, it is my choice to refund part or all of the order, or send a replacement.
Addresses are verified through Shopify, but the customer is still responsible for inputting their address in the correct format. Any returns or lost shipments, due to incorrectly addressed packages, are the responsibility of the customer.
