1、概述

是一款离线式小功率

AC/DC 开关电源的高精度原边反馈 LED 恒流

驱动电路，内部集成

600V 高压功率管，适应于 85V-265Vac 全范围输入、反激式隔离

LED 恒流驱动。通过原边控制，无需光耦等次级反馈环路，即可实现高精度的 LED 恒

流输出，降低成本。

内部集成了多重保护功能来加强系统的稳定性和可靠性，包括

VCC 欠压保护，LED 开路/短路保护，逐周期限流以及过温保护等，所有保护均具有自

动重启功能。其特点如下：

● 原边控制实现恒流，无需光耦等次级反馈环路

● 内部集成 600V 高压功率 MOSFET

● 宽电压 85Vac~265Vac 内实现高精度 LED 输出电流

● 低静态功耗

● 电感电流断续模式

● 内置前沿消隐电路（LEB）

● 输出短路/开路保护

● 电流采样电阻开路保护

● 逐周期原边电感电流限制

● 电源过压/欠压保护

● 过温保护

● 封装形式：DIP8
