LP8867-Q1: Which GND or PGND should we connect OUTX to if we don't use these OUTX?

Part Number: LP8867-Q1

Hi team,

Which GND or PGND should we connect OUTX to if we don't use these OUTX?

Datasheet says "Current sink output for LP8867-Q1 This pin must be connected to ground if not used."
Which GND or PGND does ground mean?

Hi Ochi-San.

PGND is the ground for the boost converter and GND is the ground for the current sink.

So you should connect the unused output pin to GND.
