300W 20A Step Down DC-DC Buck Converter with Constant Voltage and Current Control

Buck converter is used when you require to step down the DC voltage from a specified value to a lower value in DC voltage. Unlike AC voltage which you can control easily with a transformer, DC voltages are harder to control because you can’t use a transformer to control it and it requires switching regulators to do so. This 300W 20A DC-DC Step-down Adjustable Constant Current 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. The module has onboard multiturn potentiometers for high accuracy voltage and current regulation to provide good stability. As voltage and current are adjustable, it gives very easy to use at multiple Applications such as battery charging of multiple voltages like 12V, 9V, 3.6V, 24V, LED Driver power supply, Vehicle Power Supply, etc. i.e., it is a multipurpose module.

Symbols:
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
