8 TPS65219 VS Discrete

Table 8-1 shows a BOM size comparison between the PMIC and discrete. This BOM assumes all the PMIC power and digital rails are used in the application. The output capacitance of the PMIC Bucks depend on the selected NVM configuration (low bandwidth or high bandwidth). In this scenario, all Bucks are configured for high bandwidth which supports higher load transient but requires higher output capacitance.

Table 8-2 compares discrete with an optimized PMIC BOM where all the Bucks are configured as low bandwidth and two of the LDOs are unused.
