Size: 43mm * 21mm * 14mm (length * width * height)
Input: DC 3V to 35V (The input voltage must be more than 1.5V higher than the output voltage. Boosting is not allowed)
Output: DC voltage is continuously adjustable from 1.5V to 35V, with a maximum output current of 3A for high efficiency.
Features: All use high-quality solid-state capacitors, 36u thick circuit board, high Q value, high-power inductance with output LED indicator light
It is recommended to use a current of less than 2.5A for long-term work, and add a heat sink (output above 10W) if it exceeds 2A;
As it is a step-down module, to ensure stable output, please maintain a minimum voltage difference of 1.5V.
Precautions:
IN+input positive pole IN - input negative pole!
OUT+output positive pole OUT - output negative pole!
Note that the input and output cannot be reversed. Reverse connection may burn out!
In is connected to the input, out is connected to the output, and the positive and negative poles should not be reversed according to the label on the board! After connecting, adjust the pressure drop counterclockwise by rotating it for more than ten turns first!
1.3V -35V 3A precision adjustable power module
Wiring method
1. Welding, directly solder the power cord to the input (output) port;
2. Solder pins can be inserted through leads or used on hole boards; Alternatively, after adding pins, they can be directly soldered onto the PCB.
Application examples
