outside using the top copper layer, while tying in
PGND and LX inside (underneath) the 8-pin SO
package.
5) When trade-offs in trace lengths must be made, it is
preferable to allow the inductor charging path to be
made longer than the discharge path. For example,
it is better to allow some extra distance between the
input capacitors and the high-side MOSFET than to
allow distance between the inductor and the low-
side MOSFET or between the inductor and the out-
put filter capacitor.
6) It may be desirable to deliberately introduce some
trace length (droop resistance) between the FB
inductor node and the output filter capacitor to
meet the stability criteria (f ESR < f S / π ).
7) Place feedback resistors as close as possible to
the IC.
8) Route high-speed switching nodes away from sen-
sitive analog nodes.
9) Make all pin-strap control input connections (ILIM,
etc.) to GND or VL close to the chip, and do not
connect to PGND.
