Product Description
Module nature: Non isolated buck module (BUCK)
Input voltage: 4-35V (input cannot exceed 38V)
Output voltage: 1.25-32V continuously adjustable
Output current: 0-5A, recommended for use within 4.5A.
Output power: It is recommended to use within 75W. If it exceeds 50W, please add a heat sink.
Working temperature: -40~+85 degrees Celsius
Working frequency: 180KHz
Conversion efficiency: peak 96%
(Efficiency is related to input and output voltage, current, and voltage difference)
Load adjustment rate: S (I) ≤ 0.8%
Voltage adjustment rate: S (u) ≤ 0.8%
Short circuit protection: Yes (limited current 8A)
Overtemperature protection: Yes (automatic shutdown output after overtemperature)
Input reverse protection: None, (if necessary, please connect a high current diode in series with the input)
Installation method: 2 3mm screws (this project does not include screws)
Wiring method: Welding, V-IN as input, V-OUT as output
Module size: 44 * 21m

*PS:The output voltage of the module cannot be adjusted and is always equal to the input voltage. When you encounter this problem, please rotate the Potentiometer counterclockwise for more than 10 circles, and then use the module to adjust the voltage normally.
Because the default output voltage of the step-down module is around 20V when it leaves the factory.
