Typical Application Circuits
Layout Considerations
Due to the 1 MHz typical switching frequency of the LM3352,
careful board layout is a must. It is important to place the ca-
pacitors as close to the IC as possible and to keep the traces

between the capacitors and the IC short and direct. Use of a
ground plane is recommended. Figure 4 shows a typical lay-
out as used in the LM3352 evaluation board.
