PCB Layout Check List
When laying out the printed circuit board, the following checklist should be used to ensure proper operation of the PAM2304. These items are
also illustrated graphically in Figure 1. Check the following in your layout:
1. The power traces, consisting of the GND trace, the SW trace and the VIN trace should be kept short, direct and wide.
2. Does the V
FB
pin connect directly to the feedback resistors? The resistive divider R1/R2 must be connected between the (+) plate of C
OUT
and
ground.
3. Does the (+) plate of C
IN
connect to V
IN
as closely as possible? This capacitor provides the AC current to the internal power MOSFETs.
4. Keep the switching node, SW, away from the sensitive V
FB
node.
5. Keep the (–) plates of C
IN
and C
OUT
as close as possible.
