概览

NCV890203 是一款固定频率、单片降压开关稳压器，适合必须由高达 36 V 输入电源供电的汽车、与电池联接的应用。此款稳压器适用于汽车驾驶员信息系统中经常遇到的要求低噪声、体积小巧的系统。NCV890203 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。当输出正在调节时，重置引脚发出信号，还提供一个引脚调节 RSTB 信号进入高电平之前的延迟。NCV890203 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，高开关频率产生低输出电压纹波，即使使用小电感值和全陶瓷输出滤波电容，从而打造出了一个节省空间的开关稳压器方案。
