6.1 Always On: Power and Efficiency Optimized (-1L and -2L devices)

Figure 6-1 shows an example power map for the Power and Efficiency Optimized configuration. The rails shown follow the settings of the pre-programmed TPS6508641; however, as discussed in Section 5, the TPS650861 can also be used in this configuration.
