Optimized 72kHz max switching frequency

The iW1706 is a high performance AC/DC controller designed to drive an external power bipolar junction transistor (BJT) for peak current mode PWM flyback power supplies. Ideal for networking power supplies in applications such as ADSL modems and wireless access points, the iW1706 integrates a proprietary soft-start feature that allows for a smooth, yet fast start-up into capacitive loads between 330uF to 6000uF.

IW1706符合美国DOE的外部电源标准和欧盟的行为准则，版本5，第1层标准，无负载功耗小于100MW。作为一个PrimAccurate™使用初级侧控制算法的控制器，IW1706不需要任何直接的辅助反馈组件，无需光耦合器，降低组件计数和解决方案成本。其他功能包括对话框的专有EZ-EMI™技术，准谐振控制在重负载，电缆和连接器电压降补偿选项中的最佳效率，完全保护故障条件和微小的包装。
