8.2.2.3 Miscellaneous Passive Devices

The GREG Capacitor requires 100 nF to meet Class-D power delivery and efficiency specs. For device functionality, the GREG capacitor should be kelvin/star connected to PVDD pin of the device.

In order to maintain the device performance and keep the supply ripple within the device specification, minimizing the parasitic inductance on supply/ground paths for decoupling capacitors is required. All supply decapacitors should be selected as smallest package footprint to minimize the ESL of the capacitors. The layout placement and routing of the capacitors is critical for minimizing the trace parasitic inductance. Refer to Layout section (Section 8.5.1) to get detailed recommendations.
