The CRIO required 19-30V and the CRIO II (4 Slot) was 9-30V. The PDB would continue to provide 24V to the CRIO down to 4.5V per the spec sheet. (And in practice, we regularly saw drops to 5V in 2014 due to an intermittent short, anything less and it cut out logging)

The RoboRIO is 7-16V but instead of going through any sort of converter the PDP feeds VBat.
