Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at

Description
The FOD420, FOD4208, FOD4216 and FOD4218
devices consist of an infrared emitting diode coupled to a
hybrid random phase triac formed with two inverse paral-
lel SCRs which form the triac function capable of driving
discrete triacs. The FOD4216 and FOD4218 utilize a
high efficiency infrared emitting diode which offers an
improved trigger sensitivity. These devices are housed in
有时需要将单个电源分成两个或多个不一定相等的部分。来自干电池或汽车蓄电池的 6、12、15、24、36 或 48 V 电源就是这种情况。尽管存在精确的专用分压器 （VS），但它们可能并不容易获得或对项目而言过于昂贵。有时，设计用作 VS 的 IC 无法提供来自 VS 的所需电流或功率。 幸运的是，对于许多需要 VS 的应用，我们可以使用低成本的功率音频放大器 （PAA），例如 LM386、L...[详细]
