Figure 7.
The following equations help in choosing components of the error amplifier compensation network. Fixing the
value of the resistor R1 first is recommended as it simplifies further adjustments of the output voltage without
altering the compensation network.
where:
GOMAG is the control to output gain at desired system crossover frequency.

Introduction of output voltage droop as a measure to reduce amount of filter capacitors changes the transfer
function of the modulator as it is shown in the Figure 9.
