GENERAL DESCRIPTION

The ADM1166 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 ADM1166 integrates a 12-bit ADC and

six 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 func-

tionality at −5% of nominal supplies), or it can be used dynamically

to accurately control the output voltage of a dc-to-dc converter.
