APPLICATION INFORMATION (continued)
The droop function, as well as the output capacitor ESR, introduces zero on some frequency left of the
crossover point.
To compensate for this zero, pole on the same frequency should be added to the error amplifier transfer
function. With Type II compensation network a new value for the capacitor C2 is required compared to the case
without droop.
When attempting to close the feedback loop at frequency that is near the theoretical limit, use the above
considerations as a first approximation and perform on bench measurements of closed loop parameters as
effects of switching frequency proximity and finite bandwidth of voltage and current amplifiers may substantially
alter them as it is shown in Figure 9.
