7.4 TPS65086401 Design and Settings
The TPS65086401 device is intended to power the lower range of the Xilinx Zynq Ultrascale+ platform. An example block diagram for this system can be seen in Figure 7-6.
(1) External FETs can be scaled to
meet the current requirements of each design; CSD87381P is suitable up to
approximately 15 A.
(2) The TPS65086401 is not
limited to the ZU2CG - ZU5EG. It can support other Ultrascale+ devices as long
as the use case does not exceed the maximum specifications of the
TPS65086401.
(3) PL Domain can be optionally
powered by BUCK3, SWB1_2, BUCK5, and LDOA3 to allow it to be enabled and
disabled by CTL4. This applies only to use cases where VCCINT current is less
than 3 A.
Figure 7-6 TPS65086401 Power Map ExampleThe power up and power down sequences can be seen in Figure 7-7 and Figure 7-8. Regulators and GPOs are enabled by combination of CTL pins and regulator power good signals.
Figure 7-7 TPS65086401 Power-Up Sequence
Figure 7-8 TPS65086401 Power-Down SequenceCTL1 is used to enable the general system, CTL6 is typically connected to GPO1, and CTL4 can be used or not used depending on the application. CTL5 enables SWA1 independently of the rest of the sequence. CTL2 and CTL3 are used for BUCK6 voltage selection.
A summary of the part number specific settings can be seen in Section 7.4.1.
