Using the DS4412 to Margin the Output Voltage of a DC-DC
Converter
Abstract: A DS4412 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 a DS4412 is employed in the design.
The Adjustable Power Supply
The DS4412 contains two IC adjustable current sources capable of sinking and sourcing current. A typical
application for these
