6.1.9.8 Power Sequencing
The power up process is made up of several stages and events. Figure 26 describes the
events that make up the power up process for the processer.
Figure 26. Power Rail Power Up Sequencing
Figure 27 the voltage rail sequencing for the TPS65217C as it powers up and the
voltages on each rail. The power sequencing starts at 15 and then goes to one. That is the
way the TPS65217C is configured. You can refer to the TPS65217C datasheet for more
information.
