2.1 Load Transient Correlation Structure

Load transient response is the response to a sudden load fluctuation, which reflects the response of DC/DC converter in the period until the time until the output voltage returns to a preset value after falling or rising. In contrast with load regulation, it is the name implies a transient-state characteristic.

Load transient response can not only be tested on bench by oscilloscope, but also be simulated in Simplis and Cadence. Both bench oscilloscope waveform and simulation waveform can be saved into CSV file in each environment. After that, all the CSV data can be put into one CSV file so as to plot all the bench and simulation results in one chart for correlation analysis.

The time domain load transient correlation structure can be described as Figure 2-1.
