LMR23630 SIMPLE SWITCHER ®是一款简便易用的36V，3A同步降压稳压器。该器件具有4V至少36V的宽输入范围，适用于从非稳压源进行电源调节的各种工业应用。该器件采用峰值电流模式控制来实现简单控制环路补偿和逐周期电流限制。它具有75μA的静态电流，因此适用于电池供电型系统。凭借2μA的超低关断电流，可进一步延长电池使用寿命。内部环路补偿意味着用户不用承担设计环路补偿组件的枯风工作。这样还能够最大限度地减少外部元件数。该器件可选用恒定频率FPWM模式，在轻载条件下实现小输出电压纹波。该器件的扩展系列产品（HSOIC）能够以引脚对引脚兼容的封装（可用于实现简单且优化）的PCB布局）提供负载电流为1A（LMR23610）和2.5A（LMR23625）的选件。精密使能输入简化了稳压器控制和系统电源排序。保护功能特性包括逐周期电流限制，间断模式短路保护和过多功率耗散而引起的热关断。
