资 源 简 介
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.
