The final value of the SEQ voltage must be set higher than the set-point voltage of the Output voltage margining can be implemented in the DCM module. The output voltage follows the voltage on the modules by connecting a resistor, R margin-up, from the SEQ pin on a one-to-one basis. By connecting multiple Trim pin to the ground pin for margining-up the output modules together, multiple modules can track their output voltage and by connecting a resistor, Rmargin-down, from voltages to the voltage applied on the SEQ pin. the Trim pin to the output pin for margining-down.
