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.
