XL6009 DC-DC 5V to 48V Boost Step-Up Converter Power Supply ModuleNOTE: This datasheet is for the XL6009 BOOST converter. If you are looking for the BOOST/BUCK datasheet, go here: XL6009 DC-DC 1.5V to 35V Boost Buck Step-Up Step-Down Converter Power Supply Module Datasheet

This versatile DC-DC boost power supply / converter module accepts an input voltage from 3V to 32V and boosts it to any level from 5V to 48V (the output voltage must be at least ~1.5V greater than input voltage). Based on the second-generation XLSEMI XL6009 chip, it offers higher efficiency and superior performance than older first-generation LM2577 solutions.  


  • Wide input voltage: 3V – 32V (Optimum 5V to 32V)                
  • Fully adjustable output voltage: 5V – 48V adjustable with onboard potentiometer
  • MOSFET switching enables efficiency up to 94%
  • High switching frequency of 400KHz for low ripple and fast response time


  • Non-isolated step-up (Boost)
  • Input voltage: 3-32V
  • Input Current: 4A (Max), No-load 18mA
  • Output voltage: 5-48V continuously adjustable
  • Output current: 2.5A (Max)
  • Output power: Natural cooling 15W, plus heat sink 25W (Max)
  • Conversion efficiency: Up to 94%, varies with input voltage, output voltage and current
  • Operating temperature: Industrial grade -40 C to + 85 C (If ambient temperature exceeds 40 C, power should be derated or additional heat sinking or forced air cooling used)
  • Full load temperature rise: 45 C
  • Operating frequency: 400khz
  • Voltage regulation: ± 0.5%
  • Output Ripple: 50mV (the higher the voltage, the greater the current, the greater the ripple)
  • Load Regulation: ± 0.5%
  • Voltage Regulation: ± 0.5%
  • Short circuit protection: None (Please install fuse or protection circuit input)
  • Input reverse polarity protection: None, please use a reverse protection diode in series with the input


The 3V to 32V DC input voltage is connected to the solder pads labeled IN+ and IN-. The output voltage is connected to the load via the OUT+ and OUT- solder pads. Set output voltage using a voltmeter and onboard potentiometer before installing it in your circuit.
