Layout guidelines
1) The EDP SO-8 package of SC2596 can improve the
thermal impedance (
pad should be add when PCB layout. Some thermal vias
are required to connect the thermal pad to the PCB
ground layer. This will improve the thermal performance.
Please refer to the recommanded landing pattern.
2) To increase the noise immunity, a ceramic capacitor
of 100nF is required to decouple the V
shortest connection trace.
3) To reduce the noise on input power rail for standard
SSTL-2 application, a 100
1
input power rail with shortest possible connection.
4) VTT output copper plane should be as large as
possible. A 4.7uF to 10
decouple the VTT pin.
5) The trace between VSENSE pin and VTT rail should be
as short as possible and put a 10nF ~100nF capacitor
close this vsense pin.
