供应T5/T8 LED 日光灯管电源芯片SM2082B,芯片广泛应用于LED 路灯照明应用、LED 球泡灯,LED吸顶灯。SM2082B全新升级版,方案外围简单,钲铭科厂家低价销售
产品概述:
SM2082B是单通道LED恒流驱动控制芯片,芯片使用本司专利的恒流设定和控制技术,输出电流由外接 Rext 电阻设置为5mA~60mA,且输出电流不随芯片OUT端口电压而变化,较好的恒流性能。系统结构简单,外围元件极少,低成本方案低。
SM2082B is a single channel LED constant current driver which integrates patented constant current setting and control technology. The output current designed by external REXT is 5mA~60mA and it is invariant to OUT output voltage change, which has better constant current performance.It is a low cost circuit with simple circuit and less external components.
