USB QC3.0 QC2.0 DC-DC Buck Converter Charging Step Down Module Fast Quick Charger Circuit Board Support fast charge agreement DCP protocol, BC1.2, Apple, Samsung protocol Huawei Fast Charge Protocol FCP/SCP Huawei Fast Charge Protocol AFC Spreadtrum Fast Charge Protocol SFCP Qualcomm QC2.0 and 3.0 MTK PE1.1/PE2.0 1 USB Input voltage range: 6V-32V Output voltage: default 5V, automatically adjust between 3-12V after triggering fast charge Output power: up to 24W (5V/3.4A, 9V/2.5A, 12V/2A, etc.) Output voltage cable compensation function Conversion efficiency: 90%-97% Support multiple fast charging protocols Input overvoltage and undervoltage protection Input overcurrent protection Output overcurrent, short circuit protection Machine over temperature protection 2 USB Input voltage: DC 6~30V Output voltage: default 5V, adjust range 3~12V according to fast charging protocol Output capacity: single-port rated current 2.4A, rated power 24W Protection measures: Output overvoltage protection, limit the output voltage does not exceed 13V (in the case of chip failure); input with a fuse. 4 USB four road every support QC 3.0 quick charge agreement, all the way to support fast filling at the same time, can output 5 v and 9 v 12 v (mobile phone protocol support) voltage, output current adaptive, single channel power 24 w, 4-way module maximum power 96 w, PCB the FR - 1.6 4 mm thickness design, optimize the layout, design the beat, the back window cooling, full load working temperature is low, standby current is 0.013 A, the module has the function of the output voltage compensation. Note: this module is a 4-way voltage drop type quick charge module, please use 12v-30v DC power supply, positive and negative poles can not be connected in reverse. The module features 1. Built-in synchronous switch buck converter chip 2. Input voltage range: 4.5v to 32V (input voltage must be higher than output voltage because it is a voltage drop module) 3. Output voltage range: 3V to 12V, automatically adjusted according to the fast charging protocol 4. Output power: maximum 24W (4V-3.6A, 5V-3.4A, 9V-2.5A, 12v-2a, etc.) 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 greater than the set value, output CC mode) 7. The highest conversion efficiency is 97% 8. Soft start function 9. Switch frequency of 220Khz Multiple protection, high reliability 1, output overcurrent, input overvoltage, input undervoltage, output short circuit protection 2. Over-temperature protection of the whole machine 3. ESD 4KV, dc withstand voltage 48V All four USB channels support fast charge protocol and can output 5V 9V 12V voltage. The output voltage of USB depends on your device. The output voltage of different devices is different. The output voltage of conventional USB is 5V. #USB #QC3.0 #QC2.0 #DC-DC #Buck #Converter #Charging #Step #Down #Module #Fast #Quick #Charger #Circuit #Board
