LD8108A 08/02/2016 AC/DC Speedy Charge™ Controller for REV. 00 Qualcomm® Quick Charge 2.0 USB Interface General Description The LD8108A is an AC/DC Speedy Charge™ controller for Qualcomm® Quick Charge™ 2.0 (QC2.0) USB interface receiver for High Voltage Dedicated Charging Port (HVDCP) charger solution. The device can receive QC2.0 signal from D+ and Dof USB interface for HVDCP control. Paired with LD5718A series primary-side regulation (PSR) controllers, LD8108A will send the digital data by a single photocouplier to PSR controller and change output regulation. LD8108A provides typical 300mA discharging current for output from HVDCP voltage to 5V in order to meet a short discharge time. Active dummy load function is built in LD8108A to keep output regulation while in no load condition.
