All of the capacitors for the TPS65988 must be placed close to their respective pin. For the PP_HV1/2, VBUS1/2, VIN_3V3, LDO_3V3 it is recommended to place their capacitors on the opposite side of the TPS65988 with the GND terminal facing away from the TPS65988. This method will have all of the GND terminals together in order to have a solid plane that can be stitched to GND. The DRAIN1/2 pad will also have more room for their bottom side pour. PP_CABLE1/2 and LDO_1V8 are placed on the opposite side but their GND terminals are facing toward the TPS65988 to share the common GND pour from the TPS65988 GND pad. VBUS1/2 and PP_HV1/2 should have at least four vias to connect the TPS65988 pin, capacitors, and pours. For VIN_3V3, LDO_3V3, LDO_1V8, and PP_CABLE1/2 they can be connected with a single via to their capacitors and pours.
