Powering Up

Figure 2-8 shows the start-up waveforms for the TPS54JB20EVM. This images shows that the start-up sequence begins as soon as the EN voltage is increased above the enable-threshold voltage, and the output voltage ramps up to the externally set value of 1.0 V. The input voltage for these plots is 12 V.
