12V 24V to QC3.0 Fast Quick Charger Circuit Board USB Buck Converter Charging DC Step Down Module for Mobile Phone
Feature:
The four channels all support QC 3.0 fast charge protocol, can support fast charge at the same time, can output 5V 9V 12V (requires mobile phone protocol support) voltage, output current is adaptive.
Single channel power consumption 24W, 4-channel module maximum power consumption 96W , PCB adopts FR-4 1.6mm/0.06in board thickness design, optimized layout and wiring, strict design.
Open window on the back for heat dissipation, low full load working temperature, standby current 0.013A, and the module has an output voltage compensation function.
Note: This module is a 4-channel step-down fast charging module, please use 12V-30V DC power supply, and the positive and negative poles cannot be reversed.
Description:
This module is fully upgraded, using 2 ounces of immersion gold technology, adding a large number of heat dissipation vias, increasing the PCB bottom plate, and the charging temperature of mobile devices is basically lower.
Module characteristics:
1. Built-in synchronous switch buck converter chip
2. Input voltage range: 4.5V-32V (The input voltage must be higher than the output voltage because it is a step-down 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 reaches 97%
8. Soft start function
9. 220KHz switching frequency
Output fast charge:
1. Support for BC1.2, for Apple, for Samsung agreement
2. Support for Qualcomm QC2.0 and QC3.0
3. Support for MTK PE1.1/PE2.0
4. Support for Huawei Fast Charge Protocol FCP
5. Support for Samsung Quick Charge Protocol AFC
6. Support for Spreadtrum fast charge protocol SFCP
Multiple protection, high reliabilityL:
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
Use:
Car chargers, fast charging adapters, smart power boards, solar chargers, etc.
All four USB support fast charging protocol and can output 5V 9V 12V voltage.
