nsic2050jb: led driver, constant current regulator, 120 v, 50 ma, ±15%, for a/c off-凯发登录


rev. 1 (153kb)



该线性恒流稳流器 (ccr) 是一款简单、经济和耐用的器件,适用于为调节 led 中的电流提供经济高效的方案(与恒流二极管 ccd 类似)。该 ccr 基于自偏置晶体管 (sbt) 技术,在较宽的电压范围内调节电流。它使用负温度系数来保护 led 在极端电压和电流下不会发生热崩溃。该 ccr 将立即开启,达到 20% 调节时仅使用 0.5 v vak。它无需外部部件,因此可设计用作高压侧或低压侧稳压器。120 v 阳极-阴极电压额定值可承受离线交流应用中出现的高峰值电压。高阳极-阴极电压额定值可耐受汽车、工业和商业标志应用中常见的浪涌。
