NCV881930 是一款 410 kHz 固定频率低静态电流降压控制器，具有最高 38 V（典型值）的运行扩频。它可与时钟或单独的 NCV881930 进行同步。采用峰值电流模式控制，基于较宽的输入电压和输出负载范围实现快速瞬变响应和严格的调节。器件内部带有反馈补偿，简化了设计。NCV881930 能够以恒定基本开关频率在 3.5 V（启动时为 4.5 V）到 18 V的汽车输入电压范围内转换。在最高 45 V 的负载突降条件下，该稳压器关断。使用带有自动切换到外部 5V 偏置电源的高电压偏置稳压器来提高能效。提供 UVLO、电流限值、短路保护和高温关断等若干保护特性。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方案。（NCV891930 提供 2 MHz 版本）
