摘要
LM3445是一种与标准三端双向可控硅(TRIAC)兼容的自适应固定关断时间离线式AC/DC降压恒流LED控制器。本文主要介绍了LM3445的特点和基于LM3445的TRIAC可调光离线式LED驱动电路原理与设计。
The LM3445 is an adaptive off-line constant-current buck AD/DC LED controller with fixed off-time. It is compatible with standard TRIAC dimmer. In this paper, we introduce the main characteristics of LM3445 and then propose a TAIAC dimmable off-line diver circuit for LED based on this LM3445.
