2.2 Design Considerations

This design is intended to show the ability of the TPS6521815 PMIC to provide power to the i.MX 6ULL processor and all of the peripheral ICs in a variety of designs. To verify this, we had to populate all of these other ICs on the design, starting with the processor. All other devices necessary to build an operational data concentrator or general-purpose evaluation kit are included in this section. The PMIC and other TI devices used in this design are described in Section 2.3.
