Off-line digital green-mode quasi-resonant PWM controller

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'sPrimAccurate™和EZ-EMI®.technologies enables easy-to-design solutions and reduces BOM cost by eliminating the need for an external optical feedback isolator. The iW1709 also integrates cable drop compensation options, compensating for voltage drop in the cables and connectors, ensuring the proper voltage makes it to the load. A full complement of protection features enables robust operation in the event of a short circuit, over-voltage, input under-voltage or over-temperature condition.
