Product details of 4 Channel USB QC3.0 QC2.0 DC-DC Buck Converter Charging Step Down Module 6-32V 9V 12V 24V to Fast Quick Charger Circuit Board 3V 5V 12V

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;

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, 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.
