iP1201
Layout Guidelines
For stable and noise free operation of the whole
power system, it is recommended that the de-
signer uses the following guidelines:
1. Follow the layout scheme presented in Fig. 33.
Make sure that the output inductors L1 and L2 are
placed as close to iP1201 as possible to prevent
noise propagation that can be caused by switch-
ing of power at the switching node Vsw, to sensi-
tive circuits.
2. Provide a mid-layer solid ground plane with con-
nections to the top layer through vias. The PGND
pads of iP1201 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 iP1201, the external input decoupling
capacitors should be as close to the device as pos-
sible.
5. The Feedback tracks from the outputs V OUT1 and
V OUT2 to FB1 and FB2 respectively, should be routed
as far away from noise generating traces as pos-
sible.
6. The compensation components and the Vref by-
pass capacitor should be placed as close as pos-
sible to their corresponding iP1201 pins.
7. For single output configuration, the parasitic paths
leading to the common output connector from each
parallel branch should be symmetrically routed to
ensure equal current sharing.
8. Refer to IR application note AN-1029 to deter-
mine what size vias and copper weight and thick-
ness to use when designing the PCB.
