APPLICATION NOTE 4055
Using the DS4402/DS4404 to Margin the Output Voltage of a DC-DC
Converter

Abstract: A DS4402 or DS4404 adjustable-current DAC is used to adjust the margin of a DC-DC converter's
output voltage. This article describes how to properly select the resistor values in a DC-DC converter's feedback
divider network when a DS4402 or DS4404 is employed in the design.


The Adjustable Power Supply

The DS4402/DS4404 DACs contain two/four IC adjustable current sources capable of sinking and sourcing
