TPS2660: Figure 72. Typical PCB Layout Example With VQFN Package With a 2 Layer PCB

Hirotaka Matsumoto

Part Number: TPS2660

Hi all

Would you mind if we ask TPS2660?

On the datasheet Figure 72. Typical PCB Layout Example With VQFN Package With a 2 Layer PCB, Should NC pins connect to Top Layer RTN Plane?
Is our recognition correct?
And what does "RTN Plane" mean?

Kind regards,

Hi Hirotaka,

Yes, you can connect NC pins to RTN plane and extend the RTN Plane through NC pins on top layer for better thermal performance.
