iW1702

<75MW快速DLR的无负载电源

The iW1702 is a digital offline controller for AC/DC power supplies up to 45W optimized for 9V or greater output voltages. The part uses Dialog’s PrimAccurate™ primary-side control technology, eliminating the need for an optical isolation device on the secondary, reducing component count and cost.

对于最高功率密度电源，IW1702可以与对话框配对IW676.digital synchronous rectifier controller, which drives a power MOSFET on the secondary of the power supply to replace the main rectifying diode.

IW1702集成了独特的光负载操作模式，允许用户通过外部电阻将光负载配置最小开关频率。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.提供集成的主动电压位置（AVP）控制选项，可用于更快的DLR，同时保持无负载功耗<75mW。

A full array of protection features are integrated, includingSmartDefender™advanced hiccup technology to protect against soft shorts in cables and connectors.
