nodes of the DC/DCs.

REFBP is a noise-filtered reference, and internally

has a direct connection to the linear regulator

controller. Any noise injected onto REFBP will

directly affect the outputs of the linear regulators,

and therefore special care should be taken to

ensure that no noise is injected to the outputs via

REFBP. As with the LDO output capacitors, the

REFBP bypass capacitor should be placed as close

to the IC as possible, with short, direct connections

to the star-ground. Avoid the use of via whenever

possible. Noisy nodes, such as from the DC/DCs,

should be routed as far away from REFBP as

possible.
