Power ground, control ground routing

[Roger_tech]

I want to use the TPS63002 for a project. This IC has two ground pins, power ground and control ground. I understand that the power ground is a return path for the high current switching transistors and the control ground is a reference for the error amplifiers and other digital logic stuff. But how do I route these pins on my PCB?

Where should I connect power ground and control ground for a switched power regulator?

I'm trying to wrap my head around the concept of separating control grounds and power grounds for a switch mode power supply. I'm trying to use this TI chip in a design for regulating 3.3V, and I've
