note:

This module is a 4-way pressure drop fast charging module, please use 12V-30V DC power supply, and the positive and negative poles cannot be reversed.

Module features:

1. Built-in synchronous switch step-down converter chip

2. Input voltage range: 4.5V to 32V (The input voltage must be higher than the output voltage because it is a voltage drop module)

3. Output voltage range: 3V to 12V, automatically adjusted according to the fast charge protocol

4. Output power: 24W (4V@3.6A, 5V@3.4A, 9V@2.5A, 12V@2A, etc.)

5. Wired output voltage compensation

6. The output has CV/CC characteristics (output current is less than the set value, output CV mode; output current is greater than the set value, output CC mode)

7. Conversion efficiency reaches 97%

8. Soft start function

9. 220Khz switching frequency
