9.4.1.2.2.2 TPS25751D PP5V

The 10uF decoupling capacitor (C9) need to be placed as close as possible to the PP5V pins of TPS25751D. DO NOT use traces for PP5V. The PP5V power plane needs to be sized to support up to 3.6A (up to 3A for sourcing, 600mA for Vconn). When connecting the PP5V pins (pins 34 and 35) to the 5V power plane, use a minimum of 4 vias in parallel and close to the device to improve current sharing. Minimize the bottle necks cause by other vias or traces, large bottle necks reduces the efficiency of the power plane.

The bulk capacitors (C6, C7, and C8) represent capacitances from the system 5V rail, these are placed further away from TPS25751D on the same PP5V power plane. Refer to figure 10-14 and figure 10-15 for placement and trace reference.
