QC2.0 QC3.0 DC DC Step Down Buck Converter 10V 32V To 3.8V 12V Fast Quick Charger USB Module Board High Efficiency Mobile Phone

Sale price $1.99 Regular price $2.98

Tax included.



Input voltage range: DC10V to 32V
Output voltage: default 5V, automatically adjust between 3.8~12V after triggering fast charge (the input voltage is higher than the output voltage, if you want to trigger 12V fast charge, the input voltage should be higher than 12V).
Output power: maximum 18W (5V3.5A, 9V2A, 12V1.5A, etc.)
The output voltage is wired and complemented. When the output current increases, the output voltage is increased accordingly to compensate for the voltage drop caused by the impedance of the connection line. The current is increased by 1A and the voltage is increased by about 60mV.
Conversion efficiency: 92%~97%
Output voltage ripple: <130mV
No-load current: <2mA
Input overvoltage, undervoltage protection
Input overcurrent protection
Output overcurrent, short circuit protection
Machine over temperature protection
Product size: 33 × 20 × 10mm (length, width and height)

Supported charging protocol:
For BC1.2, For Apple, For Samsung agreement
For Qualcomm QC2.0 and QC3.0
For Huawei Fast Charge Protocol FCP
For Samsung Fast Charge Protocol AFC

Indicator description:
The blue indicator light is on after power-on, and the higher the output voltage, the higher the brightness. The orange indicator lights up when the Qualcomm, Huawei, and Samsung fast charge protocols are triggered.
