GENERAL DESCRIPTION
The ADM1066 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 ADM1066 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.
