10.6 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
F). (Since this capacitor C6 changes the start time, check the start waveform as well.) This action is not required for DAC input.
