概述:

EC4218 是一顆 3 段 LED 切換方式的線性 LED 瞘動控制芯片, 搭配 3 顆外掛功率 MOS 可以得到不同的功率輸
出(數瓦到百瓦) , 其他功能有過溫保護,當芯片表面溫度到達 90℃後開始降低功率 MOS 輸出電流來控制基板的
溫度為一定值。

特點:

● SOP 8 Exposed Pad 包裝。
● 簡單的應用電路。
● 16.75V 基納二極體等效電路, 提供內部電路使用, 不需另加 Start up HVNMOS, 方便 110V/220V 電源使用。

APPLICATIONS

● 室外燈。

ABSOLUTE MAXIMUM RATINGS

● IZ=8mA。
● Pow=18V。

Note:

Absolute Maximum Ratings are those values beyond which damage to the device may occur.
Functional Operation under these conditions is not implied. Continuous operation of the device at the absolute rating level may affect device reliability.
