1%输出纹波，解决方案小

iW1760B改进了Dialog的iW1760 AC/DC控制器的性能，将12V输出电压的输出电压纹波降低到1%，将Vcc输入电压范围提高到25V，并通过额外的保护功能增强了鲁棒性。iW1760B符合美国能源部的外部电源标准和欧盟的行为准则，第5版，tier 2标准，提供<50mW的空载功耗，同时符合有源模式最低效率要求。

The iW1760B also incorporates Dialog’sSmartDefender™smart hiccup technology to help address soft short circuits in cables and connectors. Learn more about SmartDefender smart hiccup technologyhere.
