ents The AP3171 is a constant voltage (CV), constant current (CC) and synchronous rectification buck converter compatible with Qualcomm Quick Charge 2.0. (Top View) AP3171 combines PWM controller, high/low side power MOSFETs, CC/CV control and Qualcomm QC 2.0 decoder in one package so as to achieve high performance with compact profile. According to different D+/D- signal combinations, the AP3171 will set the output voltage and full current capabilities to 5V/2A, 9V/2A or 12V/1.5A respectively. The AP3171 automatically provides 5V/2A output configuration to backwards compatible to the existing devices that are not compatib
