ADI ADP1031三路隔离微功耗管理(PMU)解决方案

ADI公司的ADP1031是具有七个数字隔离器的三路隔离微功耗管理(PMU)单元,包括隔离的反激DC/DC稳压器,反相的DC/DC稳压器和降压DC/DC稳压器.此外,还包括四个高速SPI隔离通路和三个通用的隔离器.输入电压从4.5V到60V,产生隔离VOUT1输出电压6V-28V(可调整版)或21V-24V(固定版),VOUT2为工厂可编程电压+5.15V,+5.0V或+3.3V,VOUT3为可调整输出电压-24V到-5V,主要用在工业自动化和过程控制,仪器和数据采集系统以及其数据和电源隔离.本文介绍了ADP1031主要特性, 简化框图, 应用电路图以及评估板ADP1031CP-EVALZ主要特性,电路图,材料清单和PCB设计图.

Three-Channel, Isolated Micropower Management Unit with Seven Digital Isolators The ADP1031 is a high performance, isolated micropower management unit (PMU) that combines an isolated flyback dc-to-dc regulator, an inverting dc-to-dc regulator, and a buck dc-to-dc regulator, providing three isolated power rails. Additionally, the ADP1031 contains four, high speed, serial peripheral interface (SPI) isolation channels and three general- purpose isolators for channel to channel applications where low power dissipation and small solution size is required.

Operating over an input voltage range of +4.5 V to +60 V, the ADP1031 generates isolated output voltages of +6 V to +28 V (adjustable version) or+ 21 V and +24 V (fixed versions) for VOUT1, factory programmable voltages of +5.15 V, +5.0 V, or +3.3 V for VOUT2, and an adjustable output voltages of −2
