USB QC3.0 QC2.0 USB DC-DC Buck Converter Charging Step Down Module 6-32V 9V 12V 24V To Fast Quick Charger Circuit Board 5V
Type 1 :
Input voltage range: 6V to 32V
Output voltage: The default is 5V. After the fast charge is triggered, it is automatically adjusted between 3 and 12V.
Output Power. 24W (5V, 3.4A, 9V, 2.5A, 12V, 2A, etc.)
Output voltage wired compensation
Conversion efficiency: 90% to 97%
Supports multiple fast charging protocols
Input overvoltage, undervoltage protection
Input over-current protection
Output overcurrent and short circuit protection
Over temperature protection
Type 2 :
Input Voltage: DC 10V -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 (LxWxH)
