What the supply range and quiescent current tell you
The TPS65930A2ZCH operates from 2.7V to 4.5V, which lines up with a single-cell Li-ion battery or a 3.3V regulated rail feeding an OMAP processor. The 300µA supply current is the combined quiescent draw of all internal regulators and the transceiver — that's the floor the system sees when the processor is in retention or sleep.
The 139-NFBGA (10x10) package with 0.50 mm pitch means a 4-layer board is the practical minimum for fan-out; a 2-layer board will struggle to route all signals without vias.
