[原创] Linear LTM4650－1高效多相100A降压电源解决方案

Linear公司的LTM4650-1是高效多相100A降压电源μModuleR稳压模块,DC输出总误差±0.8% (LTM4650-1A)和±1.5% (LTM4650-1B).μModuleR稳压模块封装内包括开关控制器,功率FET,电感和所有的支持元件.输入电压4.5V-15V,输出电压0.6V-1.8V,主要用在FPGA,ASIC,微处理器核电压稳压以及信息和通信系统.本文介绍了LTM4650-1主要特性,简化框图,多种应用电路以及演示板DC2455A-A特性,测试建立图,电路图和材料清单.

The LTMR4650-1A/LTM4650-1B is dual 25A or single 50Aoutput step-down μModuleR (power module) regulatorwith ±0.8% (LTM4650-1A) and ±1.5% (LTM4650-1B)total DC output error with ±3% transient output error.Included in the package are the switching controller,power FETs, inductors, and all supporting components.

External compensation allows for fast transient responseto minimize output capacitance when powering FPGAs,ASICs, and processors. With synchronized multiphaseparallel current sharing, six LTM4650-1 devices can deliverup to 300A. The LTM4650-1 is offered in a 16mm ×16mm × 5.01 BGA package, with SnPb (BGA) or RoHScompliant terminal finish.
