2.4 Power Solutions

By leveraging the simplified power requirements mentioned above, TI developed two types of low-cost power solutions for AM62x processors. The TPS65219 is the PMIC specifically designed for AM62x processors and fully leverages the simplified power requirements to provide the lowest cost PMIC for AM62x processors. A discrete power solution can provide the scalability and flexibility to adjust the power solution to be optimized for overall system requirements or meet different current capacities or the number of power supplies required by customers. Table 2-3 compares the two low-cost power solutions designed for AM62x processors.
