6) The frequency-setting resistor Rosc should be placed
close to Pin 10. Trace length from this resistor to the
analog ground should be minimized.
7) Solder the VCC decoupling capacitor next to the VCC
and power ground PGND pins.
8) Place the current-sensing components away from the
power circuit and close to the corresponding CS+ and
CS- pins. Use X7R type ceramic capacitors for current
sensing due to their thermal stability. The distance
between the two trace should be as close as possible to
minize the noise pick-up.
9) Use an isolated local ground plane for the controller
and tie it to the negative side of output capacitor bank.
10) A large copper area underneath the SC2441A IC is
nessary for heat sinking purpose. And multiple layers of
large copper area connected through vias can be used
for better thermal performance. The size of the vias as
the connection between multiple layers should not be
too large or solder may seep through the big vias to the
the bottom layer during the re-flow process.
