common Power GND node and a different node for the Signal GND to minimize the effects of ground noise.

Connect these ground nodes together to the Power Pad (star point) underneath the IC. Keep the common path

to the GND PIN, which returns the small signal components and the high current of the output capacitors as

short as possible to avoid ground noise. The FB line should be connected right to the output capacitor and routed

away from noisy components and traces (e.g., SW line).
