APPLICATION NOTE

You can also simulate the design at light load condition to check if continuous conduction mode (CCM) is
maintained for complete range of operation. You should select the maximum input voltage and minimum
load current to observe the worst case situation in this context.
Line Regulation
Now let's simulate the design to find out the line regulation of this voltage regulation module. To get the
line regulation of this VRM we need to simulate the design with known input voltage variation and
measure the output voltage against this input variation.
