NCV890200 是一款固定频率、单片降压开关稳压器，适用于汽车电池连接应用，这些应用必须在高达 36V 的输入电源下运行。该稳压器适用于汽车驾驶员信息系统中经常遇到的低噪声和小尺寸要求的系统。NCV890200 能够将典型的 4.5 V 至 18 V 汽车输入电压范围转换为低至 3.3 V 的输出，恒定开关频率高于敏感的 AM 频段，无需昂贵的滤波器和 EMI 对策。NCV890200 还提供汽车电源系统中所需的多种保护功能，例如电流限制、短路保护和热关断。此外，即使使用小电感值和全陶瓷输出滤波电容器，高开关频率也能产生低输出电压纹波 - 形成节省空间的开关稳压器解决方案。

The NCV890200 is a fixed-frequency, monolithic, Buck switching regulator intended for Automotive, battery-connected applications that must operate with up to a 36V input supply. The regulator is suitable for systems with low noise and small form factor requirements often encountered in automotive driver information systems. The NCV890200 is capable of converting the typical 4.5 V to 18 V automotive input voltage range to outputs as low as 3.3 V at a constant switching frequency above the sensitive AM band, eliminating the need for costly filters and EMI countermeasures. The NCV890200 also provides several protection features expected in Automotive power supply systems such as current limit, short-circuit protection and thermal shutdown. In addition, the high switching frequency produces low output voltage ripple even when using small inductor values and an all-ceramic output filter capacitor - forming a space-efficient switching regulator solution.
