一支工程师组织准备回答你的问题

Optimized for 5W output power applications

Integrated with a highly accurate control circuit, the iW1816 operates in a quasi-resonant mode allowing it to easily meet global energy efficiency standards, with less than 30mW of no-load power consumption.

The iW1816 includes an adaptive soft-start circuit which intelligently controls start-up over a range of output voltages from 5V to 12V and higher, and into capacitive loads up to 6000uF, making it ideal for applications such as smart meters, home appliances, and networking equipment. The iW1816 also incorporates Dialog'sPrimAccurate™初级侧数字控制算法,可实现完全隔离的解决方案,无需光耦合器,降低成本和解决方案尺寸,同时大大提高可靠性。附加功能包括从过度的温度,过度电压和电流条件以及EZ-EMI®设计技术的完全保护,以允许容易满足全球EMI规范的解决方案。
