Power Supply Mapping

TPS65917 or TPS659039 are the Power Management ICs (PMICs) that should be used for the Device designs. TI requires use of these PMICs for the following reasons:

  • TI has validated their use with the Device
  • Board level margins including transient response and output accuracy are analyzed and optimized for the entire system
  • Support for power sequencing requirements (refer to Section 5.9Power Supply Sequences)
  • Support for Adaptive Voltage Scaling (AVS) Class 0 requirements, including TI provided software

Whenever we allow for combining of rails mapped on any of the SMPSes, 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. e.g. 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:

  • The AVS voltage of active rail in the combined rail needs to be used to set the power supply
  • The decoupling capacitance should be set according to the active rail in the combined rail

Table 8-4 illustrates the approved and validated power supply connections to the Device for the SMPS outputs of the TPS659039 PMIC.

  1. Power consumption is highly application-specific. Separate analysis must be performed to ensure output current ratings (average and peak) is within the limits of the PMIC for all rails of the device
  2. Dual phase (SMPS1/2) can be used as long as the peak power consumption is maintained below the SMPS1/2 capacity
    1. For the latest rated output current specifications for the TPS659039 device, please refer to the PMIC data manual.
    2. MPU power consumption is highly system dependent. A detailed power consumption estimate must be performed to confirm compatibility. Example: Single vs Dual MPU, OPP_NOM vs OPP_OD vs OPP_HIGH, TPS659039 configured with VI≥3V vs VI<3V, etc. Contact your TI representative for details.
  3. Combination 3 must only be used in systems where the MPU frequency is 1 GHz or lower. If greater than 1 GHz MPU is required, then the vdd_mpu domain must be powered independently.
  4. Refer to the PMIC data manual for the latest TPS659039 specifications
  5. A product’s maximum ambient temperature, thermal system design & heat spreading performance could limit the maximum power dissipation below the full PMIC capacity in order to not exceed recommended SoC max Tj

  1. Refer to the TPS65917 Data Manual for exact current rating limitations, including assumed VIN and other parameters. Values provided in this table are for comparison purposes.
  2. DSP, EVE, GPU, and IVAHD power consumption is highly application-specific. Separate analysis must be performed to ensure output current ratings (average and peak) is within the limits of the PMIC. VDD only supports OPP_NOM.
  3. Highly application-specific. Separate analysis must be performed to ensure average and peak power is within the limits of the PMIC.
  4. Furthermore, if SMPS5 is used for DDR power, both total memory + SoC power must be within the PMIC limits.
