[6] Transient response
Normally, IOUT is suddenly changed while VIN and VOUT are maintained constant, responsiveness including the
response time and overshoot/undershoot voltage is checked. As this IC has built-in Error Amp with an optimized
design, it shows good transient response characteristics. However, if ringing upon sudden change of the load
is high due to the operating conditions, add capacitor C6 (e.g. 0.1 μF). (Since this capacitor C6 changes the
start time, check the start waveform as well.) This action is not required for DAC input.
