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。
