2.10 Powering Up and Down
The start-up voltage waveform of the TPS54350EVM235 is shown in
Figure 212. The waveform shows the nominal 12-V input voltage in Ch. 1, the
3.3-V output ramping up in Ch. 2 and the PWRGD signal in Ch. 3. Note that
the PWRGD signal is pulled up externally to 3.3 V.

The corresponding power down waveform is shown in Figure 213 The
channel assignments are the same as in the power up waveform above.
