The ADM1069 Super Sequencer® is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems. In addition to these functions, the ADM1069 integrates a 12-bit analog-todigital converter (ADC) and four 8-bit voltage output digital-toanalog converters (DACs). These circuits can implement a closedloop margining system that enables supply adjustment by altering either the feedback node or reference of a dc-to-dc converter using the DAC outputs. For more information about the ADM1069 register map, refer to the AN-721 Application Note.
