产品概述

描述

L7983器件是一款降压型单片式开关稳压器，能够基于峰值电流模式架构提供高达300 mA DC。

输出电压可调范围为0.85V至V_IN。较宽的输入电压范围和可调节的UVLO阈值符合12 V、24 V和48 V工业总线标准规范。

低功耗模式”（LCM）是专为在空闲模式下处于活动状态的应用而设计的，因此它可以在输出电压纹波受控的轻负载下最大限度地提高效率。“低噪声模式”(LNM)使开关频率在负载电流范围内保持恒定，以满足低噪声应用规范。L7983支持动态LCM至LNM的过渡。

软启动时间为内部固定，且输出电压监控器管理任何数字负载（微控制器、FPGA等）的复位阶段。

内部补偿网络具有较高的抗噪声能力，设计简单且节省组件成本。

RST开路集电极输出还可在开机阶段实现输出电压排序。

同步整流设计用于中重负载时的高效率，高开关频率功能使应用程序的大小变得紧凑。

两个功率元件上的脉冲电流感应实现了有效的恒流保护。
