iW1709
PrimAccurate™ Digital Off-Line Controller with <50mW No-Load Power Consumption for Power Supplies up to 12W
离线数字绿色模式准谐振PWM控制器
IW1709数字离线控制器提供快速启动，进入高电容负载，非常低的待机功耗（<50MW）和成本优化的BOM，使用低成本的BJT电源设备，用于离线电源，最多12W。通过将美国能源部外部电力供应效率要求和第5版，欧盟外部电源行为准则的第2层，IW1709理想地适用于家庭网络设备，家电，无线接入点和机顶盒。
Integrating Dialog's PrimAccurate™ and EZ-EMI®技术支持易于设计的解决方案，并通过消除外部光学反馈隔离器的需求来降低BOM成本。IW1709还集成了电缆掉落补偿选项，请补偿电缆和连接器中的电压降，确保正确的电压使其成为负载。保护功能的完整补充使得在短路，过电压，输入欠压或过温条件的情况下，可以实现鲁棒操作。
ADiaSIM™simulation model is available for the iW1709. For more information and where to download, please visit theDiaSIM™page.
