The traces of power feedback lines must be surrounded by output power plane, or
crosstalk from other signals will cause voltage instability and oscillation
，
as shown in Fig 5-29.

All input and output capacitors should be placed close to RK818, and enough via holes
should be placed around them to guarantee the signal return path, especially to input and
output capacitors of large current power supply.
