Buck Converter Modules are used to step down a high DC voltage to low voltage. This module also lets your set the maximum current that can be drawn at the output. The required output voltage and current can be set by the user by tuning onboard potentiometers using a screwdriver. Suitable for LED Drivers, Motor Drivers, and any application where output voltage and current has to be regulated.

The 300W 20A DC-DC Buck Converter Step Down Module is a handy power accessory board that allows you to fine-tune the amount of power your project receives. This converter can take an input voltage of anywhere from 6V to 40V DC(10V to 40V is suggested) and regulate it to an output voltage between 1.2V to 36V DC.

The module is designed with a 75V/80A large current dual MOS tube. The buck module has 2 heat sink that could enhance heat dissipation. Wiring is convenient with these large current 30A screw terminals. The efficiency can be up to 96%, measured at 20A, converting 24V to 12V.

Note: When there is a big difference between input and output voltage, please decrease power and current.


  • Input Voltage: 6V to 40V DC(10V to 40V is suggested)
  • Output Voltage: 1.2V to 36V DC
  • Output Current: 20A(max.), 15A(suggested)
  • Efficiency: 95%(24V to 12V, 20A)
  • Output Ripple: ≤50mV
  • Wiring Method: Terminal
  • Short Circuit Protection: Self-recovery(cannot short circuit for a long time)
  • Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06"

Pin Description:

  • VO+: Output positive
  • VO-: Output negative
  • +IN: Input positive
  • -IN : Input negative
  • CV: Output voltage adjustment
  • CC: Output current adjustment

When input and output is common grounded, no-load CV output constant voltage, CC output constant current

Package Include:
1 x 300W 20A Constant Current Adjustable Buck Converter Step-Down Voltage Module
