二次侧控制器允许快速充电QC2.0支持的移动设备

The iW629 is aRapid Charge™二次侧接口和通信IC，与iW1780一次侧AC/DC数字控制器配合使用，支持用于智能手机和平板电脑电源的低成本Qualcomm Quick Charge 2.0适配器解决方案，具有双层电缆保护功能。

The iW629 integrates Dialog’s proprietary secondary-to-primary digital communication technique using an optocoupler to relay commands to the iW1780 AC/DC controller. The iW629+iW1780 chipset provides efficiency as high as 88% to enable the higher power density needed for small form-factor fast charging adapters.

iW629为USB连接器上的D+/D-引脚提供了专有的过压保护功能，该功能与SmartDefender™advanced hiccup technology integrated in the iW1780, provides cable soft-short protection on both the primary and secondary sides. Learn more about SmartDefender advanced hiccup technology here.
