LX1689集成电路（IC）的照明镇流器控制器规格书PDF中文资料

LX1689属于集成电路（IC）的照明镇流器控制器。由美高森美半导体公司制造生产的LX1689照明，镇流器控制器此产品族中的产品可用于实现控制和调节功能。对于日光灯、电致发光灯和 HID 灯等非 LED 照明工具的正常工作，这些功能很有必要或十分有用。既定器件所具备的特定功能集因预期用途各异，并且所供应的产品可能包括相应资源以直接控制驱动负载的电源，也可能不包括这些资源。

DESCRIPTION

The LX1689 is the latest generation Direct Drive CCFL (Cold Cathode Fluorescent Lamp) Controller. It uses new circuit design techniques (patents pending) and combines digital and linear circuits with an advanced BiCMOS process to create a more complete controller in a small package.

When compared to the original LX1686 design, identical module applications use from 12 to 30 less components. New functions and enhancements have been added to make the LX1689 even easier to use.
