IW657P.

支持s USB Power Delivery 3.0, Qualcomm^®快速充电™4+，直接充电适配器

IW657P USB电源输送（USB PD）3.0接口控制器位于AC / DC电源的次级侧，并管理电源适配器和移动设备之间的通信。

IW657P与对话框合作（IW1791.那IW1797.那IW1799）RapidCharge™primary-side controller and supports fast charging protocols, including USB PD 3.0, Qualcomm Quick Charge 4+ and direct charging. It transmits all necessary information via an optocoupler to the primary side, including voltage requests, output current limits, output voltage undershoot, output over-voltage, and fault and reset signals. It also offers an optional secondary-side current sensing circuit to provide additional over-load fault protection.

IW657P也适用于对话框IW676.synchronous rectifier, which eliminates the need for a parallel Schottky diode for higher efficiency and lower BOM cost.
