BoostXL-DRV8301 3.3VDC leg - Is it the DVDD output?

Other Parts Discussed in Thread: BOOSTXL-DRV8301, DRV8301

On the schematic for the BoostXL-DRV8301, there are many references to +3.3V. Is that connected to the DVDD (pin no. 23) on the board?

Hi Alan,

It is not from DVDD (that is a internal regulator for the DRV8301).

+3.3V is supplied from the DRV8301 buck regulator.

So output PH, pins 50 & 51?

Correct, PH is the switching output from the buck regulator.
