300W DC-DC Buck Converter-

The 300W DC-DC Step-down Converter Power 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 it 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).

This 300W DC-DC Buck Converter Module is made from a dedicated benchmark IC and high-precision current sensing resistor, providing a more stable constant current, (when 20C to 100C constant current 1A, temperature drift less than 1%); therefore it is particularly most suitable for LED driver applications. The output current of the module can be raised up to 20A(for continuous use it is recommended up to 15A with an additional cooling fan).

This 300W DC-DC Buck Converter Power Module has onboard 3296 multiturn potentiometers for high accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, it is very easy to use for multiple Applications such as battery charging, LED Driver power supply, Vehicle Power Supply, etc. which makes the module Multipurpose hence this module is always in demand from our maker because of its wide range of application and low cost.

To enhance the stabilization in output voltage it has six high-frequency capacitance which gives the 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.

Features

  • With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust the output voltage and current.
  • The efficiency can be up to 96%, measured at 20A, converting 24V to 12V.
  • It is designed with a 75V/80A large current dual MOS tube.
  • Input and output use high-frequency low resistance electrolytic capacitors, low ripple, and stable output.
  • Wiring is convenient with these large current 30A screw terminals.
  • The 300W DC-DC Buck Converter Module has 2 heat sinks that could enhance heat dissipation.
  • When there is a big difference between input and output voltage, please decrease power and current.

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 to shut off the output; suspension, the high voltage level is effective

How to do 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)

Applications

  • Lithium battery(or lead accumulator) charge
  • Low voltage power supply system
  • High-power LED driver
  • Vehicle-mounted power supply
  • Regulated power supply
  • Low voltage system power supply
  • 6V, 12V, 14V, 24V battery charge
  • On-board laptop power supply
