Texas Instruments LM4360x SIMPLE SWITCHER® 稳压器

德州仪器 LM4360x SIMPLE SWITCHER® 是易于使用的同步降压型直流-直流转换器，能以 3.5V 到 36V 范围的输入电压，驱动高达 3.0A 的负载电流(瞬时 42V)。LM4360x 以非常小的尺寸提供优异的效率、输出精度和压差。采用了峰值电流模式控制，以实现对环路补偿和逐周期电流限制的简单控制。它还具有可编程开关频率、同步、电源正常标记、精密启用、内部软启动、可扩展软启动、跟踪等可选特性，为广泛应用提供了灵活、易于使用的平台。轻负载条件下的非连续传导和自动频率调制提高了轻负载效率。该系列仅需少量外部元件，而其引脚排列有助于简单、最优的 PCB 布局。保护特性包括热关断、VCC 欠压闭锁、逐周期电流限制、输出短路保护。
