Proprietary primary-secondary communication technology

The iW620 is a Rapid Charge™, AC/DC adapter interface IC that resides on the secondary side of the AC/DC power supply and works with Dialog’s iW1760B(40W) and iW1699B(12W) primary-side digital PWM controllers to enable Qualcomm Quick Charge 2.0 technology-compliant power supplies for smartphones and tablets. Efficiency as high as 88% enables the higher power density needed for smaller form-factor fast charging adapters.

Qualcomm快速充电2.0技术规范允许适配器输出的电压定位，以便将充电时间降低多达电流充电时间的75％。IW620可确保可编程，专利的主动快速输出电压放电的安全操作，从9V或12V降至5V。因此，当USB电缆从高QualcomM快速充电2.0技术启用的手机拔出时，然后使用非快速充电2.0手机使用时，IW620迅速将输出电压降至5V，以保护手机免受损坏。

在5V下工作时，IW620进入待机模式，绘制小于120UA的电流，允许整体解决方案保持小于30MW的无负载功耗。

The iW620 is UL verified. Read the UL Verification Certificate for the iW620.
