Using this device for 24V -> 12V generation.
In order to reduce losses, we are considering applying 5V (generated from a completely separate supply) to the BIAS pin (pin #9)
The 5V supply we are considering would be applied to BIAS pin at some yet-unknown timing, and there could be times when that rail decreases down to 0V occasionaly.
Is it still possible to use such a 5V rail for the BIAS?
We are assuming that when the BIAS voltage isn't enough, the internal LDO's source would automatically switch between PVIN <-> BIAS, and would operate without issue...
So only the power consumption (loss) would be affected.
Is this understanding correct?
