说明

LMR23630 SIMPLE SWITCHER® 是一款易于使用的 36V、3A 同步降压稳压器,具有 4V 至 36V 的宽输入电压范围,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燥工作。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。该器件的扩展系列米6体育平台手机版_好二三四 (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。利用精密使能端输入可以简化稳压器控制和系统电源时序。保护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。
