Transient Response
The output voltage measured at the converter output pins on the system board is within the transient range
shown in Table 3. The transient response is measured with DC – 200 MHz frequency bandwidth, and at
ambient temperatures between 0
°C and 70 °C.
Typical transient response and noise waveforms are shown in Figures 5 – 16.
