ADI LTM4673数字电源系统管理功能四路输出μModule稳压器解决方案

ADI公司的LTM4673是集成4通道电源系统管理器的四通道输出双通道12A和双通道5A的开关模式DC/DC降压μModule(电源模块)稳压器, 用于排序,调整(伺服),裕量调节,监控,管理故障,提供遥测并创建故障日志.LTM4673在4.5V至15V的输入电压范围内工作,12A通道的输出电压范围为0.6V至3.3V,5A通道的输出电压范围为0.6V至5.5V.仅需要大容量输入和输出电容.LTM4673具有双线式串行接口,可对输出进行精确地裕量调节,微调和可编程上电和关断时序控制.内部16位ADC可监控输入和所有四个输出电压,电流和温度.可对四个输出通道的过流和欠电流,电压和温度阈值限制以及输入过压和欠压进行故障编程.LTM4673采用16mm × 16mm × 4.72mm BGA封装,提供符合RoHS标准的端子表面.主要用在电信,网络和工业设备,多轨负载点调整以及FPGA,DSP和ASIC应用.本文介绍了LTM4673主要特性,框图,多种应用电路, 演示板DC2810A主要特性和测量设备建立图,电路图和材料清单.

 

The LTMR4673 is a quad output, dual 12A and dual 5A, switching mode DC/DC step-down μModule (powermodule) regulator integrated with 4-channel Power System Manager used to sequence, trim (servo), margin, supervise, manage faults, provide telemetry, and create fault logs. Operating over an input voltage range of 4.5V to 15V, the LTM4673 supports an output voltage range of 0.6V to 3.3V for 12A channels and 0.6V to 5.5V for 5A channels. Only bulk input and output capacitors are needed.

The LTM4673s 2-wire serial interface allows outputs to be precisely margined, tuned and programmable sequenced up and down. An internal 16-bit ADC monitors and supervises input and all four output voltages, curre
