ADP2114 GND

Discussion created by power-layout-guy on May 15, 2014

I attempted to answer your question in the post but it appears the post is locked and I cannot reply. So I decided to start a new post.

 

The Data sheet states

pin 19 PGND4 Power Ground. Source of the low-side internal power MOSFET of Channel 2.

pin 20 PGND3 Power Ground. Source of the low-side internal power MOSFET of Channel 2.

pin 21 PGND2 Power Ground. Source of the low-side internal power MOSFET of Channel 1.

pin 22 PGND1 Power Ground. Source of the low-side internal power MOSFET of Channel 1.

 

I do not know if they are connected in the IC. What I can tell you is that, we connect them all together on the EVAL board. See attached schematic and picture. I hope this helps. Maybe someone else will answer.
