3pcs QC2.0 QC3.0 Fast Quick Charger USB Module Board High Efficiency DC-DC Step Down Buck Converter

Specifications: ? Input voltage range: 10V to 32V DC 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 Sam sung agreement For QC2.0 and QC3.0 For Huawei Fast Charge Protocol FCP For Sam sung Fast Charge Protocol AFC ? Applications: ? Solar panel to mobile phone charging Car charging retrofit Driving recorder power supply Switching power supply transformation ? Package Included: ? 3 x High Efficiency DC-DC Step Down Buck Converter 10V-32V To 5V QC2.0 QC3.0 Fast Quick Charger USB Module Board
