Qualcomm Quick Charge 3.0 Charger Reference Design Evaluation Board

The NCP4371QC30GEVB Evaluation Board is designed to effectively evaluate the NCP4371, which is a USB secondary side fast-charging controller, supporting Qualcomm Quick Charge™ 3.0 (QC 3.0) High Voltage Dedicated Charging Port (HVDCP) Class A and Class B specification. NCP4371 allows for selection of the output voltage of an AC-DC USB adapter based on commands from the Portable Device (PD) being powered. Selecting a higher charging voltage will reduce the charging current for a given power level resulting in reduced IR drops and increased system efficiency. Another advantage of QC3.0 is a decreased battery charging time and a reduced PD system cost thanks to the ability to select an optimum charging voltage. This eliminates the need for costly DC-DC converters within the PD. The USB-bus voltage can be controlled in discreet steps from 3.6V up to 20V. The output current is limited not to exceed maximum allowable power level.
