SMM665, 605, 205, 105 Supply Voltage Marginers and Active DC Output Controllers COMPONENT SELECTION FOR OPTIMUM PERFORMANCE

PAGE 3

SUMMARY The SMM665/605/205/105 family ADOC and Margining features achieve very high accuracy control of DC-DC converters, LDO's and other power supply regulators. They also have the added benefit of true user programmable ADOC and Margin voltage settings along with many other valuable features useful for monitoring, sequencing and reacting to the performance of system power supplies. Flexible operation and in-field changes are made possible using the device's programmable, non-volatile configuration and General Purpose memory array.
