Layout Guidelines
For stable and noise free operation of the whole
power system, it is recommended that the design-
ers use the following guidelines:
1. Follow the layout scheme presented in Fig. 23.
Make sure that the output inductor L is placed as
close to iP1203 as possible to prevent noise propa-
gation that can be caused by switching of power at
the switching node Vsw, to sensitive circuits.
2. Provide a mid-layer solid ground plane with con-
nections to the top layer through vias. The PGND
pads of iP1203 also need to be connected to the
same ground plane through vias.
3. To increase power supply noise immunity, place
input and output capacitors close to one another,
as shown in the layout diagram. This will provide
short high current paths that are essential at the
ground terminals.
4. Although there is a certain degree of V IN bypass-
ing inside the iP1203, the external input decoupling
capacitors should be as close to the device as pos-
sible.
5. The feedback track from the output V OUT to FB
should be routed as far away from noise generating
traces as possible.
6. The compensation components and the Vref by-
pass capacitor should be placed as close as pos-
sible to their corresponding iP1203 pins, away from
noise generating traces.
7. Refer to IR application note AN-1029 (Optimizing
a PCB Layout for an iPOWIR Technology Design) to
determine what size vias and copper weight and
thickness to use when designing the PCB.
8. Place the overcurrent threshold setting resistors
R OCSET close to the iP1203 block at the correspond-
ing connection node.
