NCP3065 是一款单片降压升压逆变开关稳压器,用于为高亮度 LED (HBLED) 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,NCP3065 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,也可在铅酸电池等无调节电源下运行。该器件可在增加一个外部晶体管的控制器拓扑结构中配置,支持内部晶体管额定 1.5 A 开关电流以上的 LED 电流。NCP3065 开关稳压器可配置在步降(降压)、步升(升压)或 SEPIC 拓扑结构中,外部部件数量极少。提供启用功能,零件编号 NCP3066。
