may be required to improve noise
filtering. This provides a low impedance path for filtering
the high frequency noise. All high current loops should be
kept as short as possible using heavy copper runs. The
error amp compensation circuitry and the converter out-
put voltage-divider should be located close to the IC and
as far as possible from the power switch and other noise
generating components.
