用保證金控制和非易失性故障記錄超級(jí)音序器ADM1169數(shù)據(jù)表

　　The ADM1169 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 ADM1169 integrates a 12-bit ADC and four 8-bit voltage output DACs. These circuits can be used to implement a closed-loop margining system that enables supply adjustment by altering either the feedback node or reference of a dc-to-dc converter using the DAC outputs.

　　Supply margining can be performed with a minimum of external components. The margining loop can be used for in-circuit testing of a board during production （for example， to verify board functionality at ?5% of nominal supplies）， or it can be used dynamically to accurately control the output voltage of a dc-to-dc converter.
