Hi Charlie,
For Triboard, all needed voltages are generated via Infineon’s Multi Voltage Safety Micro Processor Supply TLF35584QV and via the microcontroller itself (+1,25V).
The supply device is available as two different devices:
TLF35584QVVS1 -> +5V standby voltage, +5V TriCore™ supply (V_UC)
TLF35584QVVS2 -> +3,3V standby voltage, +3,3V TriCore™ supply (V_UC)
Dependent of the assembled device the board works with 5V or 3,3V IO.
The TLF35584QV provide the following voltages:
+3,3V or +5V for standby (connected to VEVRSB)
+3,3V or +5V for TriCore™ (connected to VEXT)
+5V communcation supply (used by CAN and FlexRay™ transceivers)
+5V voltage reference (connected to VDDM and VAREFx)
+3,3V via LDO directly from pre regulator
Applying a stable supply voltage causes the power on reset after a short period. The three LED's (V_UC, +3.3V,
VDD) indicate the status of the on board generated voltages.
A manual power on reset is executed by pressing the reset button.
The Board has to be connected to a +3,5V to +40V DC power supply.
The power consumption is not specified yet but a supply with 12V and 500mA is recommended. \
Below is screenshot of the sch for your reference which is from TriboardManualxxx.pdf

Otherwise, you could refer to AURIXTC3xx_ts_part1_v2.5.1.pdf HWCFG[2:1] setting explaination of Table 466 Supply Mode and Topology selection as below showed:
