LTM4601EV-1#PBF 数据手册 - Linear Technology（凌力尔特）
制造商:
Linear Technology（凌力尔特）
分类:
DC/DC转换器
封装:
LGA-118
描述:
Module 调节器，单输出**Linear Technology** 的直流/直流 μModule （微模块）调节器提供电源管理解决方案，带系统封装 (SiP)。 这将包含一个集成直流/直流控制器、补偿组件、功率晶体管、电感器和输入和输出电容器。 μModule 支持步降（降压）功能，可以在一些产品中提供一个低 EMI 符合 EN55022 B 类标准的解决方案，具有源和阱电流能力。 特别适合用于电信和网络设备、工业设备和 ATCA 卡/服务器之类的应用。 ### 开关电压调节器，Linear Technology**Linear Technology** 的同步型和非同步型内部开关调节器 IC 产品系列效率高、输入电压范围广、且开关频率高达 4 MHz。 该系列控制器包括多种配置：从降压（下降），升压（上压）、降压-升压、正向、隔离、反相和反激控制器。 反激、正向和隔离控制器（一次侧和二次侧）提供解决方案，帮助更换背板型电源转换中使用的直流/直流砖型转换器。
