Digital Power System Managers
Analog Devices power system managers allow you to keep existing analog power systems while adding new capabilities: output trimming (±0.25% precision), margining, sequencing, nonvolatile fault recording, and digital monitoring data (on voltage, current, power, energy, temperature, and faults). Our portfolio spans a wide range of channel counts (2 to 16 supplies) and easily manages even larger POL power systems found in network routers and switches, servers, enterprise data storage systems, and automated test equipment.
This portfolio uses digital I2C/SMBus interfaces, LTpowerPlay® software, and internal EEPROM with several customization options.
