Item Type: Buck Converter_x000D_ Supported Protocols: For QC2.0, for OC3.0, MTK PE1.1 2.0, for IOS, for Samsung AFC, for Huawei FCP, for Spreadtrum SFCP_x000D_ Input Voltage: 6V to 32V (input voltage must be higher than output voltage since it is a buck module)_x000D_ Output Voltage: 3V to 12V, automatically adjusted according to the fast charging protocol. _x000D_ Output Power: maximum 24W (4V 3.6A, 5V 3.4A, 9V 2.5A, 12V 2A, etc.)_x000D_ Conversion Efficiency: Up to 97%_x000D_ Protection Measures: Output over voltage protection, in case of chip failure, the limit output voltage should not to exceed 13V. Input with fuse. 5V output with line compensation function, when the output current increases, the output voltage will be slightly increased to compensate for line loss. _x000D_ Application: For solar panel to mobile phone charging, car charging conversion, driving recorder power supply, household power supply, smart power strip conversion, fast charging adapter. 1Quick Charging: Supports various quick charging protocols, such as for QC2.0, for OC3.0, MTK PE1.1 2.0, for IOS, etc. 2Reliable Works: If the output current is less than the set value, outputs in CV mode, otherwise, outputs in CC mode. 3Extensive Uses: Suits for solar panel to mobile phone charging, car charging, driving recorder power supply and so on. 4Working Safety: Comes with over voltage protection and input with fuse, there is low line loss and high work safety. 5Better Designs: Built in synchronous switching buck converter chip and soft start function enable stable operation.1 x_x000D_ _x000D_ Buck Converter
