Here are some key points you might find in the documentation or specifications of a typical adjustable buck converter module:

1. Input Voltage Range: The range of input voltages that the converter can accept.
2. Output Voltage Range: The adjustable range of output voltages that can be set by the user.
3. Output Current: The maximum current the module can supply at the specified output voltage.
4. Efficiency: The efficiency of the converter, which indicates how effectively it can convert input power to output power.
5. Adjustment Method: Information on how the output voltage can be adjusted. Some modules have a potentiometer for manual adjustment, while others might support external voltage control.
6. Protection Features: Overcurrent protection, overvoltage protection, and other safety features to prevent damage to the module and connected devices.
7. Size and Form Factor: The physical dimensions and mounting options of the module.
8. Application Notes: Guidance on how to use the module effectively and any specific considerations for your application.
