概览

CS5141X 产品为 1.5A 降压稳压器集成电路。这些器件以 260kHz 和 520kHz 固定频率运行。此类稳压器使用 V2 控制结构为当今的高速逻辑提供无与伦比的瞬变响应、最佳总体调节，以及最简单的环路补偿。这些产品可容纳从 4.5V 至 40V 的输入电压。CS51411 和 CS51413 包含了同步电路。CS51412 和 CS51414 可以选择从外部 3.3V 至 6V 电源为控制器供电，以提高能效，尤其在高输入电压、轻负载情况下。片上 NPN 晶体管能够提供最小 1.5A 的输出电流，通过外部“升压”电容器进行偏置，以确保饱和，因此最大程度降低片上功耗。保护电路包括高温关断、按周期电流限制和频率折回。CS51411 和 CS51413 可与 LT1375 实现引脚兼容。CS51412 和 CS51414 可与 LT1376 实现引脚兼容。
