iW626 AC/DC Secondary-Side Controller for Qualcomm® Quick ChargeTM 2.0 USB Interface and Secondary-Primary Communication 1 Description The iW626 is an AC/DC secondary-side controller for QC2.0 USB interface and secondary-primary communication. The device allows rapid charging of QC2.0-enabled PDs. The iW626 resides on the secondary side of an AC/DC power supply and allows the adapter to be configured for 5V, 9V, or 12V output depending on the voltage requested by QC2.0 enabled PD. It can be used in Dialog’s primary-side controlled AC/DC systems to achieve fast voltage transition, low no-load power consumption and fast dynamic load response. The iW626 implements Dialog’s proprietary secondaryto-primary digital communication technique. When paired with Dialog’s primary-side controller iW1780, the iW626 eliminates the discrete decoders in the primary side and simplifies system designs. The iW626 uses one opto-coupler to transmit all necessary information for rapid charge, including output voltage requests, output current limits, output voltage undershoot and output over-voltage. It also has a built-in opto-coupler LED driver to minimize the bill of material cost. Dialog’s innovative proprietary technology ensures that power supplies designed with the iW626 and iW1780 can provide 5V/9V/12V output voltage configuration, with user-selected various output current limit combinations. Furthermore, the chipset can achieve <10mW no-load power consumption at 5V2A output setting and fast dynamic load response in typical AC/DC HVDCP adapter designs.
