GENERAL DESCRIPTION
The ADM1062 is a configurable supervisory/sequencing device which offers a single chip solution for supply monitoring and sequencing in multiple supply systems.
In addition to these functions the ADM1062 integrates a 12-bit ADC and six 8-bit voltage output DACs. These circuits can be used to implement a closed loop margining system. This enables supply adjustment by altering either the feedback node or reference of a DC/DC Converter using the DAC outputs. The supply margining can be performed, with a minimum of external components, to an accuracy of 0.5%. The margining loop can be used at In Circuit Testing of a board during production (to verify the board’s functionality at say −5% of nominal supplies), or can be used dynamically to accurately control the output voltage of a DC/DC converter.

APPLICATIONS
   Central office systems
   Servers/routers
   Multivoltage system line cards
   DSP/FPGA supply sequencing
   In circuit testing of margined supplies
