LED 驱动器,可调恒定电流稳压器,50 V,150 - 350 mA

Favorite

概览

该可调恒定电流稳压器 (CCR) 是一款简单、经济和耐用的器件,适用于为 LED 中的调节电流提供成本高效的方案(与恒定电流二极管 CCD 类似)。该 (CCR) 基于自偏置晶体管 (SBT) 技术,基于较宽的电压范围调节电流。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。恒定电流稳压器将立即开启,25% 调节时仅使用 0.5 V Vak。Radj 引脚通过在 Radj(引脚 3)和阴极(引脚 4)之间连接一个电阻,使得 Ireg(SS) 能够调节为更高电流。如果无需条件,Radj 引脚还可以保持开路状态(无联接)。它无需外部部件,因此可设计用作高压侧或低压侧稳压器。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电涌。该器件采用耐高温封装,无引线且符合 RoHS 要求,使用无卤素成型复合件。满足 AEC-Q101 标准要求,获得 UL94-V0 认证。
