概览

NCV890130 是一款固定频率、单片降压开关稳压器,适合必须由高达 32 V 输入电源供电的汽车、与电池连接的应用。该稳压器适用于具有低噪声和小外形要求的系统,通常汽车驾驶员信息系统有此要求。NCV890130 能够将典型的 4.5 V 到 18 V 汽车输入电压以高于敏感的 AM 频带的恒定开关频率转换为低至 3.3 V,无需成本高昂的滤波器和 EMI 应对措施。NCV890130 还提供汽车电源系统中应具有的若干保护功能,如电流限值、短路保护和高温关断。此外,即使使用较小的电感器值和全陶瓷输出滤波电容器,高开关频率也会产生较低的输出电压纹波,从而成为节省空间的开关稳压器方案。
