9.4.2 Operation With Vi > 200m – VRMS

For input voltages greater than 200m-VRMS, the bandwidth depends directly from the loop filter capacitance and free running frequency product. Bandwidth is represented as a percentage of the free running frequency, and according to the product of f0∙C2, it can have a variation from 2 to 14%. Table 9-2 shows the approximate values for bandwidth in function of the product result.
