APPLICATION NOTE 4280
Using the DS4424 to Margin the Output Voltage of a DC-DC
Converter

Abstract: A DS4424 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 of a DC-DC converter's feedback
divider network when the DS4424 is employed in the design.


Introduction

The DS4424 adjustable-current DAC is similar to the DS4404 adjustable-current DAC with two major differences.
First, the DS4424 has 127 settings each for……
