Applications Information (Cont.)

The transient response for a maximum load step changes (10A to 60A) is shown in Fig. 14, where one can see that

accurate drooping will help to reduce the amount of output capacitance needed. Please notice that using more

multilayer ceramic capacitors for better high frequency decoupling can reduce the narrow voltage spikes.
