iW1790

Supports Qualcomm® Quick Charge™ 3.0 and 2.0 without Optocoupler; Companion to the iW662 Rapid Charge™ and Synchronous Rectifier Controller IC

The iW1790 is a 27 W output, high performance AC/DCRapidCharge™power supply controller that integrates Dialog’sXM-Comm技术，从旅行适配器中删除所有光耦合器，以降低成本并提高可靠性。该器件还采用先进的源计费技术集成了额外的高压元件，进一步降低了旅行适配器应用中的整体BOM成本。亚博国际官网平台网址该设备支持高通量3.0和2.0以及其他快速充电协议。

It is optimized to work with Dialog’siW662二次侧设备，其集成了速度充电interface IC and a synchronous rectifier controller. TheiW662uses Dialog’sXM-Comm技术将所有必要信息传输到IW1790，包括电压请求，输出电流限制，输出电压下划线，输出过电压和故障和复位信号。

A full array of protection features includes Dialog’sSmartDefender™advanced hiccup technology to address soft short circuits in charger cables and connectors, helping to prevent excessive heat build-up and damage.
