1 System Description

Figure 1-1 shows that the TIDA-010241 reference design is comprised of various power components:

  • The TPS53688 controller is configured in a 6 + 2 phase configuration. The six-phase output is used for the core rail of the FPGA, while the two-phase output is used for secondary core power.
  • The TPS650861 PMIC has three controllers, three converters, and VTT LDO that are configurable and has flexible sequencing via software. The TPS650861 also has additional GPIOs that can be used to control external converters, or controllers for sequencing, or utilize both attributes.
  • The TPSM5D1805 devices are used for any extra rails as well as providing an intermediate 5-V rail required by the three converters on the TPS650861
