3.4 Load Transient

Figure 3-4 Load Transient of the Single Converter and Dual Converter

Figure 3-4 shows the load transient response to a load increase from 4.5 A to 12 A in 1 μs and a decrease back to 4.5 A with the same slope for both converter implementations. The single converter implementation (VOUT1) and the dual converter implementation (VOUT2) show no difference in maximum voltage deviation. The output voltage settling shows minor differences though. This is caused by the different component values required for R1 and C1 in the compensation network.
