Kétirányú gyorstöltés és lecsökkentő modul 12V24V - QC3.0 gyorstöltés, kettős USB töltőkártya támogatja az Apple Huawei FCP-t
2 way fast charge and step-down module 12V24V to QC3.0 fast charge, dual USB charging board supports Apple Huawei FCP
Module characteristics
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: maximum 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. The conversion efficiency is up to 97%
8. Soft start function
9. 220Khz switching frequency
Output fast charge

Multiple protection, high reliability
1. Output overcurrent, input overvoltage, input undervoltage, output short circuit protection
2. The over-temperature protection of the whole machine
3. ESD 4KV, DC withstand voltage 48V
Use
The USB output voltage of car chargers, fast charging adapters, smart power strips, solar chargers, etc. depends on your device. The output voltage of different devices is different. The conventional USB output voltage is 5V. It can output different fast charging voltages according to the QC protocol. Generally, the fast charging voltage of mobile phones is 9V 12V, and some devices support 5V high-current fast charging, and devices that do not support fast-charge charging with low current.
