4.2.1 DC-DC Operating Limits
The maximum supported voltage on the VDD supply pin is limited under certain conditions. Maximum input voltage is a function of tem-
perature and the average load current over a 10-year lifetime. Figure 4.1 Lifetime average load current limit vs. Maximum input voltage
on page 10 shows the safe operating region under specific conditions. Exceeding this safe operating range may impact the reliability
and performance of the DC-DC converter.

Figure 4.1. Lifetime average load current limit vs. Maximum input voltage
The minimum input voltage for the DC-DC in EM0/EM1 mode is a function of the maximum load current, and the peak current setting.
Figure 4.2 Transient maximum load current vs. Minimum input voltage on page 10 shows the max load current vs. input voltage for
different DC-DC peak inductor current settings.
