UM3510
Layout Guidance
When laying out the PC board, the following suggestions should be taken to ensure proper
operation of the UM3510.
1. The power traces, including the GND trace, the SW trace and the VIN trace should be kept
short, direct and wide to allow large current flow.
2. Connect the input capacitor C_IN to the VIN pin as closely as possible to get good power filter
effect.
3. Keep the switching node, SW, away from the sensitive FB node.
4. Do not trace signal line under inductor.
