Digital Power System Management

Digital Power System Management

Analog Devices digital power system management (PSM) products help you simplify and accelerate power system characterization, optimization, and data mining during prototyping, deployment, and field operation. Our PSM products are configured and monitored through a PMBus/SMBus/ I²C digital interface. Our engineering-level development environment, LTpowerPlay^®, provides control and monitoring of power supply voltage, current, power and energy use, sequencing, margining, and black box fault log data. This industry-leading development software with graphical user interface (GUI) has been proven to support up to 256 voltage rails.

µModule Regulators with Digital Power System Management

Analog Devices μModule^® (micromodule) regulators with a PMBus I²C serial interface, also called PSM (power system management), enable system designers and remote operators to command and supervise a system’s power condition and consumption via a digital bus. The ability to digitally change power supply parameters reduces time-to-market and downtime by eliminating what would have historically required physical hardware, circuits, and/or system bill-of-material modifications. Our μModule regulators simplify system characterization, optimization, and data mining during prototyping, deployment, and field operation. This portfolio uses digital I²C/SMBus interfaces, LTpowerPlay^® software, and internal EEPROM with several customization options.

Boost Regulators with Digital Power System Management

Analog Devices boost regulators with digital power system management (PSM) provide accurate information about power systems and autonomously control and supervise dozens of voltages with ease. They provide high accuracy programming and telemetry with on-board EEPROM parameters that include voltage and current, sequencing, operating frequency, margining, faults, and temperature. Our devices are supported by LTpowerPlay^®, a powerful and intuitive Windows-based development software tool used to configure and interrogate PSM devices. When deployed, PSM devices are seamlessly integrated with existing embedded systems and architectures.

Buck Regulators with Digital Power System Management

Analog Devices buck regulators with digital power system management (PSM) provide accurate information about power systems and autonomously control and supervise dozens of voltages with ease. They provide high accuracy programming and telemetry with on-board EEPROM parameters that include voltage and current, sequencing, operating frequency, margining, faults, and temperature. Our devices are supported by LTpowerPlay®, a powerful and intuitive Windows-based development software tool used to configure and interrogate PSM devices. When deployed, PSM devices are seamlessly integrated with existing embedded systems and architectures.

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.
