Current Sharing
Figure 25 shows the current balancing between the two phases for different values of output current.
Figure 25.
Load Transient Response
Figure 26 shows the system response from 0 to 50A load transient. To obtain such a response, 5 additional
capacitors have been added to the output filter to reproduce the motherboard output filter. Noise can be further
reduced by adding ceramic decoupling capacitors.
