iW1760B

45W AC/DC Off-Line Controller for Power Adapters Offers Lower Output Ripple, Wider Input Voltage vs iW1760

一支工程师组织准备回答你的问题

1%输出纹波,小型解决方案尺寸

IW1760B通过将输出电压纹波降低到12V输出电压的输出电压纹波来提高对话的IW1760 AC / DC控制器的性能,从而增加VCC输入电压范围高达25V并增加额外保护功能的鲁棒性。IW1760B通过提供无负载功耗<50MW的同时符合主动模式最低效率要求,符合美国DOE的外部电源标准和欧盟的行为准则,第5版,第2层标准,而是通过符合主动模式最低效率要求。

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
