General Description
This device includes two specialized N-Channel MOSFETs in a
dual PQFN package. The switch node has been internally
connected to enable easy placement and routing of synchronous
buck converters. The control MOSFET (Q1) and synchronous
SyncFET (Q2) have been designed to provide optimal power
efficiency.

... Power Stage is a high power density solution and all high current flow paths, such as VIN (D1), PHASE (S1/D2) and GND (S2), should be short and wide for better and stable current flow, heat radiation and system performance.

... Vias should be relatively large, around 8 mils to 10 mils, and of reasonable inductance. Critical high frequency components such as ceramic bypass caps should be located close to the part and on the same side of the PCB.
