Buck Boost Circuit




This module power output is affect by the module itself-capacity and pre-and post-class load and other factors; the following data for professional equipment measured results, without considering other factors.Power supply module is a kind of electronic components, please don’t buy the item if you have no electronic expertise.
This Module Properties: It is non-isolated step-down constant current, constant voltage module (CC CV) charging module.


  1. Input Voltage :4-35V
  2. Output voltage: Continuously adjustable(1.25-25V unload adjust)
  3. Output current: 3A Max(If more than 15W, please install the heat sink)
  4. CC range :0-2A (adjustable)
  5. Revolving light current: CC value * (1%-100%), default is 0.1 times
  6. Minimum voltage difference: 2V
  7. Output power: natural cooling 15W
  8. Conversion efficiency: 80% (the higher the output voltage, the higher the efficiency)
  9. Operating Temperature: Industrial (-40 degree to +85 degree) (ambient temperature more than 40degree, lower power use, or add heat sink)
