7.2 Typical Application

The TPS65215-Q1 PMIC contains five regulators; 3 Buck converters and 2 Low Drop-out Regulators (LDOs). In addition to the power resources, it also integrates 3 configurable multi-function pins, 1 GPIO, 2 GPOs and I2C communication making this power management IC a cost and size optimized solution to power multiple processors and SoCs. There are several considerations to take into account when designing the TPS65215-Q1 to power a processor and peripherals. The number of regulators needed, the required sequencing, the load current requirements, and the voltage characteristics are all critical in determining the number of supply rails as well as the external components used with it. The following section provides a generic case. For specific cases, refer to the relevant user's guide and TRM based on the orderable part number.
