특징
-
1.Built-in synchronous switch buck 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

5.Wired compensation of output voltage
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 up to 97%
8. Soft start function
9, 220Khz switching frequency
Output fast charge
1.Support BC1.2, Apple, Samsung protocols

문서
- The output voltage of USB depends on your device. The output voltage of different devices is different. The conventional USB output voltage is 5V. According to the QC protocol, you can output different fast charging voltages. Generally, the fast charging voltage of mobile phones is 9V 12V, and some devices support 5V high current fast charging. , Does not support fast charging of small current devices.
