3.4 Start-up and Shutdown Sequence

Figure 3-5 displays the start-up waveform at 48Vin input into a no load. The total rise time is 3.4ms, insinuating total start-up totaling about 4.25ms.

Figure 3-8 displays the shutdown waveform at 48Vin input into a ⅓Ω constant-resistance load using an electronic load. The total fall time is 37.2ms, insinuating total shutdown totaling about 46.4ms.
