DC Buck Module, DROK Adjustable Buck Converter Step Down Voltage Regulator 6V-32V 30V 24V 12V to 1.5-32V 5V 5A LCD Power Supply Volt Reducer Transformer Module Board with USB Port Protective Case
Brand: DROK

Parameters：
Chip: MP2304
Input voltage: 6~32V
Output voltage: 1.5~32V continuously adjustable (Input should be 1.5V higher than output.)
Output current: 5A max, adjustable, recommended use within 4.5A. (Over 3A or 35W, please enhance heat dissipation.) Constant current requires an output voltage of above 2V to be adjusted. Current regulation can only be performed in the status of constant current.
Output Power: 75W (max), recommended use within 50W. Please reduce the power when voltage difference is large.
Operating temperature: -20℃ to +70℃
Operating frequency: 180KHz
Conversion efficiency: up to 96%
Short circuit protection: Yes (Constant current value set by constant current function)
Over-temperature protection: Yes (Automatically shut off the output when overtemp.)
Input reverse polarity protection: Yes
Output backflow prevention: None. Please add a diode when used for charging.
Installation: 8x pillars, 8x 3mm screws
Wire Connection: terminal block or soldering terminals; VIN is input; VOUT is output.
Dimension: 65.6*40*25mm

Display Modes:
1). F-0 mode: Display output voltage
2). F-1 mode: Display input voltage
3). F-2 mode: Display input and output voltage alternately
4). USB mode: Display USB output voltage & turn on/off USB output

Note:
Output is set as around 20V before leaving factory, if your input is lower than that, please turn potentiometer anticlockwise for at least 10 laps until voltage changes.

Package Included:
1x DC Buck Module
4x Copper Cylinder Screws M3*6
4x Double-pass Screws M3*12
8x Roundhead Screws M3*6
