11 Layout

11.1 Layout Guidelines

1. PP5V, PPHV, and VBUS traces must be as short and wide as possible to accommodate for high currents.

2. A ceramic 10 uF (X7R/X5R) 10-V rated capacitor coupled with a 0.1-uF high frequency capacitor placed, is

placed as close as possible to the PP5V terminal of the TPS6602x.

3. Care should be taken to ensure the ground return of RIREF is in close proximity to the GND terminal of the

TPS6602x to minimize error in the current limit setting due to voltage drops that may occur across the

ground supply.

4. A ceramic 4.7 uF (X7R/X5R) 10-V rated capacitor is placed as close as possible to the VLDO terminal of the

TPS6602x.
