TIDA-00366: Regarding net VCC_U (VCC_V & VCC_W)

Part Number: TIDA-00366
Other Parts Discussed in Thread: UCC21520, TL431, AMC1301

UCC21520 Vdda is given at 16V using Bootstrap while the net VCC_U will also be at 16V U_TOP_REF. but VCC_U is also used for giving supply for ADC using TL431 keeping VDD1 at 5V. Is this interpretation Correct.

It means 16V - 5V is dropped across the R72 820ohm resistor.
