4 Channel DC Buck Module 12V24V to QC3.0 Single USB Mobile Charging Board

Description:

 

1. The module all supports fast charging, and each channel has independent chip control.

Each independent input capacitor and output capacitor, independent energy storage integrated inductor,  independent self-recovery fuse, all four independent output.

2. Each channel supports 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 adaptive, single channel power consumption 24W, 4-channel module maximum power consumption 96W, PCB Adopt FR-4 1.6mm plate thickness design, optimize layout and layout, design is tight, back window heating, full load working temperature is low, standby current is 0.013A, module has output voltage compensation function

 

Features:

 

- Built-in synchronous switch buck converter chip

- Output voltage wired compensation

- 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) 

- Conversion efficiency up to 97%

- Soft start function

- Output over current, input over voltage, input under voltage, output short circuit protection

- ESD 4KV, DC withstand voltage 48V

 

Specifications:

 

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

Output voltage range: 3V to 12V (automatically adjusted according to the fast charge protocol)

Output power: maximum 24W (4V3.6A, 5V3.4A, 9V2.5A, 12V2A, etc.)

Switching frequency: 220Khz

Output fast Charge:

1. Support BC1.2

2. Support Qualcomm QC2.0 and QC3.0

3. Support MTK PE1.1/PE2.0

4. Support Huawei Fast Charge Protocol FCP

5. Support  fast charge agreement AFC

6. Support Spreadtrum Fast Charge Protocol SFCP

Application: Car charger, fast charge adapter, smart socket, solar charger, etc.

 

Note:

 

1. This module is a 4-channel voltage drop type fast charging module. Please use 12V-30V DC power supply. The positive and negative poles can't be reversed.

2. Buying a module requires a certain amount of hands-on ability, and the module requires a soldering iron wire.
