Product Details Supplier Info More products

Analog Devices announces the Power by Linear ADM1266 Super Sequencer, a highly programmable device for monitoring, sequencing, and margining up to 17 power supplies. For larger rail counts, a proprietary 2-wire inter-device bus synchronizes the operation of 16 ADM1266s. A built-in sequencing engine monitors each supply fault detector, general purpose inputs/outputs, and timers to turn the supplies on and off in a user-determined sequence. All configuration is performed through the intuitive ADI Power Studio GUI, reducing design time. The ADM1266 provides a highly flexible yet simple solution to manage complex power systems on FPGA, ASIC, and processor boards in network routers and switches, servers and data storage systems.

The ADM1266 integrates an analog-to-digital converter (ADC) and nine voltage output digital-to-analog converters (DACs) that adjust the feedback node or reference of a DC-to-DC converter to implement a closed-loop, autonomous margining system. A nonvolatile EEPROM records voltage, time, and fault information when instructed by the sequencing engine configuration, speeding fault debug.

The ADM1266, along with the ADI Power Studio software, offers a feature-rich configurable state machine to meet complex sequencing requirements. Built-in debugging features like breakpoints and black box, along with the software setup wizards, reduce development and debug time from days to a matter of hours. The inter-device bus between multiple ADM1266s ensures they perform like a single device, providing for an intuitive design process. By handling all complexity, the software fashions a seamless design experience from 17 rails to 257 rails.

Specified over the −40^oC to 85^oC temperature range, the ADM1266 is offered in a 64-pin 9mm x 9mm LFCSP package. Device samples and evaluation circuit boards are available online or from your local Analog Devices sales office. For more information, visit www.analog.com/ADM1266.
