Compact DC-DC Step-Up Converter Module. The output voltage is adjustable via the blue trimmer.


  • size: 34 x 32mm(LxW).
  • input (3.7V ~ 34V), output (3.7V ~ 34V), can be adjusted.
  • Maximum input current 3A, it s better to work below 2A, Power up to about 15W, up to about 90% efficiency.
  • Use coarse wire circuitry. Clockwise voltage decrease, Counterclockwise the voltage increases.
  • Positive and negative input and output can not be reversed, the output can not be short-circuit.
  • Output voltage must be limited to 35V or less, otherwise it will damage the circuit.
  • As is the step-up DC-DC circuit, so the input voltage is lower than the output voltage. To ensure stable output voltage.
  • Input and output voltage as close as possible, Input Voltage * Input Current * efficiency = output voltage * Output current. The closer the input and output voltage output current increases!

Note: This can not be used for notebook, laptop power need at least 60W. The following is the maximum input current 3A test results, for reference:
