Analog Devices announced the introduction of the ADM1266, a new Power by Linear Super Sequencer that can be programmed to monitor, sequence, and margin up to 17 power supplies.

If more than 17 rails are required, up to 16 ADM1266 devices can be cascaded and synchronized using a proprietary 2-wire interdevice bus.

A built-in sequencing engine monitors each power fault detector, general-purpose input/output (GIO), and timer to power supplies on and off in a user-defined sequence. All configurations can be handled through the ADI Power Studio GUI, reducing design time. The ADM1266 manages complex power systems on FPGAs, ASICs, and processor boards, as well as network routers and switches, servers, and data storage systems.

The ADM1266 integrates one ADC and nine voltage-output DACs to regulate the feedback node or reference of a DC/DC converter implementing a closed-loop autonomous margining system. Nonvolatile EEPROM speeds up error debug by recording voltage, time, and error information when instructed by the sequencing engine settings.

In addition to support for ADI Power Studio software, the ADM1266 offers a feature-rich, configurable state machine that meets complex sequencing requirements. Built-in debugging features such as breakpoints and black boxes, along with a software setup wizard, reduce development and debug time from days to hours.

The interdevice bus connects multiple ADM1266 devices, allowing them to operate as a single device, ensuring an intuitive design process. From as few as 17 rails to as many as 257 rails can be connected.

The ADM1266 operates over the −40°C to 85°C temperature range and is available in a 64-pin, 9 mm x 9 mm LFCSP package. Samples and evaluation boards are available online or from your local Analog Devices sales office.
