Description:
The 300W DC-DC Buck Converter Module can be used to get adjustable output voltage ranges from 1.2V to 36V. The module provides a wide range of current output up to 20 A. With the heat sink mounted 300W DC-DC Buck Converter can easily manage to run high-power applications continuously (provided that for continuous high-power output, you need to use a cooling fan on the heat sink). The 300W DC-DC Buck Converter is made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable constant current, (when 20°C to 100°C constant current 1A, temperature drifts less than 1%); therefore it is particularly most suitable for LED driver applications. The output current of the 300W DC-DC Buck Converter can be raised to 20A(for continuous use it is recommended up to 15A with an additional cooling fan).
To enhance the stabilization in output voltage there are six high-frequency capacitances which give a lower output ripple. The double heat sink design provides easy and fast heat dissipation. MOS Schottky diode independent heat sink, which heat dissipation is good, and won’t affect each other. Also using large-size Sendust Core and double pure copper wiring improves working efficiency, and reduces fever. The 300W DC-DC Buck Converter has onboard 3296 multiturn potentiometers for high-accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, the 300W DC-DC Buck Converter is very easy to use for multiple applications such as battery charging, LED Driver power supply, Vehicle Power Supply, etc.

Pin Description:
- VO+: output positive
- VO-: Negative output
- +IN: Enter the positive polarity
- -IN: Input the negative pole
- CV: Output voltage adjustment
- CC: Output current adjustment
- EN: Enable, low voltage level shut off output; suspension, high voltage level is effective
Module Adjustment:
- When the module output voltage cannot be adjusted (the output voltage is always equal to the input voltage) Please adjust the potentiometer counterclockwise 20 laps (20 turns) or more till it works.
- Turn trimmers CLOCKWISE to INCREASE, ANTICLOCKWISE to DECREASE.
- When adjusting the blue potentiometer, please use a multimeter to monitor the voltage
- The trimmer nearest the voltage output adjusts the output CURRENT (CC)
- The trimmer nearest the voltage input adjusts the output VOLTAGE (CV)
