多相升压器 LED 驱动器,用于汽车前照明

添加至我的收藏

概览

NCV78702 是一款单芯片、高能效升压器,用于汽车前照明应用的智能电力镇流器和 LED 驱动器,这些应用有远光灯、近光灯、日间行车灯 (DRL)、转向指示灯、雾灯、静态转弯灯等。NCV78702 特别针对高电流 LED 而设计,与 NCV78723(双沟道降压)/713(单沟道)提供驱动最高 60 V 的多个 LED 串的完整方案。它包括了电流模式升压控制器,还可用作输入滤波器,且外部组件数量极少。可用输出电压可定制。可以将两个 NCV78702 器件组合在一起,并可与升压电路一起运行,其功能相当于多相升压器(2 相、3 相、4 相),从而进一步优化升压电路的滤波效应,并降低应用物料总成本,提高功率。由于 SPI 可编程能力,一个硬件配置可以支持多个应用平台。
