<30MW无负载功率使用自适应电压定位控制IC（IW676）

The iW1602 is a digital offline AC/DC controller for up to 30W output travel adapters. It uses Dialog’sprimAccurate™初级侧控制技术消除了对二次光隔离装置的需要，减少了部件计数和成本。

IW1602集成了独特的光负载操作模式，允许用户通过外部电阻将最小开关频率配置在光负载下。光负荷模式开关频率越高，动态负载响应越好（DLR）。如果选择了最低开关频率，则减少空载功耗，对DLR性能产生负面影响。在这种情况下，iW676具有集成主动电压位置（AVP）控制的同步整流器控制器可用于更快的DLR，同时保持空载功耗<30mW。

The iW1602 integrates a full array of protection features, including Dialog’sSmartDefender™先进的HICCUP技术，以防止旅行适配器电缆和连接器中的软短路。了解有关SmartDefender智能HICCUP技术的更多信息这里.
