All pads on the iP1206 footprint design need to be Solder-mask defined (see Figure 26).
Place as many vias around the Power pads (VIN, VSW, and PGND) for both electrical and optimal thermal
Vias in between the different power pads may overlap the pad opening and solder mask edge without the need
A minimum of six 10µF, X5R, 16V ceramic capacitors per iP1206 are recommended for the lowest loss due to
Placement of the ceramic input capacitors is critical to optimize switching performance. In cases where there is
Dedicate at least two layers for PGND only.
Duplicate the Power Nodes on multiple layers (refer to AN1029).
