NEW PRODUCT AP43331N QUICK CHARGER CONTROLLER COMPATIBLE WITH QUALCOMM QC3.0 Description The AP43331N is a highly integrated secondary side constant voltage (CV) and constant current (CC) controller, which is compatible with Qualcomm Quick Charge 3.0 (QC 3.0) High Voltage Dedicated Charging Port (HVDCP) Class A specification. Pin Assignments (Top View) The AP43331N allows for selection of the output voltage of an AC−DC USB charger 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. The USB−bus voltage can be controlled in discreet steps (QC 3.0’s step is 0.2V).
