this phenomenon and why in Circuit Cellar magazine in the last few
months. If I can dig up the text from their electronic copy, I'll
post it here.<br>

Gist of it is, you minimize ground loops and signal paths where
real-world parts and materials have impedance and generate noise
and oscillations. More specifically you minimize power ground
noise from the control signals.<br>

I'll revisit the email list config parameters with respect to

I think the TI spec is saying your "control ground" paths go from
their various places to one point ("A") and the power ground paths
go from their places to another point ("B") and "A" and "B" are
connected at exactly one point. The figure for the parameter
measurement information on page 11 of the datasheet shows this
clearly.<br>
