Transient Analysis is a tool simulating the output voltage response under a user defined loading current profile. The tool has a simplistic interface allowing users to use a set of points to define the current loading profile by current level at different times. The tool will combine a small signal approach and large signal analysis to simulate the output voltage change against time.
If the user has already selected a design, this tool will inherently retrieve all necessary parameters from the design and show the corresponding result at just the click of the mouse.
If no design is selected, the tool will assume a power supply with a loop response defined in ¡°Equivalent Output Circuit¡±.

Users can modify the loading waveform. The loading waveform is shown on the left while usesr can modify the waveform on the right. After any modification, click [Apply] to update.
Users can change the frequency of the loading waveform.
Two types of waveform are provided. Users can choose between step loading waveforms or sine loading waveforms. Users can also modify the detail value for each type of waveform.
Click [Advanced User Setting]. Users can set the output impedance of a generic power supply by setting "Output Capacitor", "Output Inductor", "Loading Capacitor", "Max. positive supply current" and "Min. negative supply current" to customize the generic power supply characteristics.
