该LM3481是一种多用途的低侧N - FET的开关稳压器的高性能控制器。 它是用于要求在拓扑a所LM3481可以在非常高的开关频率操作,从而降低整体解决方案尺寸低边FET,如升压,反激式,SEPIC等,适合 该LM3481开关频率可以调整到任何介于100 kHz和1 MHz的价值通过使用一个外部电阻器或同步至外部时钟。 电流模式控制提供除逐周期电流限制高带宽和瞬态响应。 电流限制可以通过编程用一个外部电阻。

已建成的LM3481,如热关断,短路保护和过电压保护保护功能。 A power-down shutdown mode provides 5μA total supply current and allows power sequencing. Internal soft-start limits the surge at start-up current.
