LED 驱动器，恒流稳流器，用于 A / C 离线应用
Obsolete
概览
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，并且仅需 0.5 V Vak 即可实现 45％ 的调节。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-阴极电压还可保护工业和商业标志应用中常见的浪涌。该 CCR 采用耐高温封装，已获得 UL94-V0 认证。
