TPS659163 or LP8733 are the Power Management IC (PMIC) that should be used for Device designs. TI requires use of this PMIC for the following reasons:
Whenever we allow for combining of rails mapped on any of the SMPSs, the PDN guidelines that are the most stringent of the rails combined should be implemented for the particular supply rail. It is possible that some voltage domains on the device are unused in some systems. In such cases, to ensure device reliability, it is still required that the supply pins for the specific voltage domains are connected to some core power supply output.
These unused supplies though can be combined with any of the core supplies that are used (active) in the system. For example, if DSP domain is not used, they can be combined with the CORE domain, thereby having a single power supply driving the combined CORE and DSP domains.
For the combined rail, the following relaxations do apply:
