PRODUCTION DATA.
TPS65917 and LP87565 are the Power Management ICs (PMICs) that are used on the TI EVM. TI recommends use of these PMICs on customer designs for the following reasons:
Other PMIC combinations have been analyzed and are recommended by TI in order to optimize for particular use cases. These options require additional analysis and validation to be performed by the customer. Contact your TI representative for additional details. In all cases, the customer’s specific use case power estimate should be analyzed, and confirmed to be supported for any chosen implementation.
If multiple SoC voltage domains are allowed to be combined into a common board power rail, the most stringent recommended PDN guidelines (Table 7-3) should be applied to the common power 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 IVA and GPU domains are not used, they can be combined with the CORE domain, thereby having a single power supply driving the combined CORE, IVA and GPU domains.
For the combined rail, the following relaxations do apply:
