The printed-circuit-board (PCB) layout is an
important step to maintain the high performance of
the TPS62A01x-Q1 device.
- The input, output capacitors and the inductor
must be placed as close as possible to the IC.
This action keeps the power traces short. Routing
these power traces direct and wide results in low
trace resistance and low parasitic inductance.
- The low side of the input and output capacitors
must be connected properly to the GND pin to avoid
a ground potential shift.
- The sense traces connected to FB is a signal
trace. Special care must be taken to avoid noise
being induced. Keep these traces away from SW
nodes.
- A common ground must be used. GND layers can be
used for shielding.
See Figure 8-15 for the recommended PCB layout.
