1% output ripple, small solution size

The iW1699B improves on the performance of Dialog’s iW1699 AC/DC controller by reducing the output voltage ripple to 1% on a 12V output voltage, increasing the Vcc input voltage range up to 25V, and increasing robustness with extra protection features.

IW1699B可轻松符合美国DOE的外部电源效率标准和欧盟的行为准则，第5版，第2层外部电源标准，无负载功耗小于30MW，同时遵守最小的主动模式效率要求。

IW1699B还包含对话框SmartDefender™智能打嗝技术帮助在电缆和连接器中介入软短路。了解有关SmartDefender先进的HICCUP技术的更多信息here。

The iW1699B is pin-to-pin and backward compatible with theiW1699。
