PRODUCT SPECIFICATION
FAN2534/FAN2535
General PWB Layout Considerations
For optimum device performance, careful circuit layout and
grounding technics must be used. Establishing a small local
ground, to which the GND pin, and the output and bypass
capacitors are connected, is recommended, while the input
capacitor should be grounded to the main ground plane.
The quiet local ground is then routed back to the main
ground plane using feedthrough vias. In general, the high-
frequency compensation components (input, bypass, and
output capacitors) should be located as close to the device as
possible. The proximity of the output capacitor is especially
important to achieve optimum performance, especially
during high load conditions. A large copper area in the local
ground serves as heat sink (as discussed above) when high
power dissipation significantly increases device temperature.
Component-side copper provides significantly better thermal
performance. Added feedthrough connecting the device side
ground plane to the back plane further reduces thermal
resistance.
