iW636

iW636 AC/DC Secondary-Side Controller for Qualcomm® Quick ChargeTM 3.0 USB Interface 1 Description The iW636 is an AC/DC secondary-side controller for USB interface supporting Qualcomm Quick Charge 3.0 (QC3.0) technology and secondary-to-primary communication protocol, to enable rapid charging of QC3.0/QC2.0-enabled mobile devices (MDs). The iW636 resides on the secondary side of an AC/DC power supply and allows the adapter to be configured for multi-level output voltages from 3.6V to 12V in 200mV increments, depending on the voltage requested by the MD. 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 iW636 implements Dialog’s proprietary secondary-to-primary digital communication technique. When paired with Dialog’s primary-side iW1782 controller, the iW636 eliminates the discrete decoders on the primary side, simplifying system designs. It uses one opto-c...
