20A 300W Synchronous Buck Module DC Step Down Voltage CC Power 5V 12V 24V 36V


  • ⚡ This step-down voltage module with a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current.

  • ⚡ It is designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output.

  • ⚡ The efficiency can be up to 96%, measured at 20A, converting 24V to 12V. Wiring is convenient with these large current 30A screw terminals.

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

  • ⚡ The buck module has 2 heat sink that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current.

  •  Features & Tips

  • VO+: Output positive

    VO-: Output negative

    +IN: Input positive 

    -IN: Input negative

    CV: Output voltage adjustment

    CC: Output current adjustment

    EN: Enable, low voltage level shut off output; suspension, high voltage level is effective

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


    Maintain stable output voltage and limit the output current over a range of input voltages. Great for general voltage conversion, battery charging, powering raw LEDs, automotive electronics, battery conversions, micro-controllers, and electronic projects.

    Input Voltage: 6-40V DC • Output Voltage: 1.25-36V DC • Max Load: 300W/20A Peak, 15A Sustained

    Minimum Dropout: 3V • Conversion Efficiency: Up to 96% • Short-circuit protection • Non-isolated

    Dimensions: 60x53x27mm • LM25116 IC • 150KHz Switching Frequency • 50mV ripple

    Input must be at least 3V more than the output voltage. Applying reverse polarity voltage to the input or output may damage the module. A fan is required if the module temperature exceeds 65°C
