降压/升压/逆变稳压器,开关,恒定电流,1.5 A,用于带启用的 HB-LED

Favorite

概览

NCP3066 是一款单片降压升压逆变开关稳压器,用于为高亮度 LED 提供恒定电流供电。该器件具有 235 mV(标称值)的极低反馈电压,用于调节 LED 串的平均电流。另外,NCP3066 具有很宽的输入电压范围,最高可达 40 V,因此可在照明应用常用的 12 Vac 或 12 Vdc 电源下运行,也可在充电电池等无调节电源下运行。NCP3066 开关稳压器可配置在步降(降压)、步升(升压)和反向电压拓扑结构中,外部部件数量极少。提供 NCV3066 汽车版本,与 NCP3065 一样不带开关功能。
