PC Board Layout Checklist

When laying out the printed circuit board, the following checklist should be used to ensure proper operation of the

AME5253. These items are also illustrated graphically in Figures 9. Check the following in your layout:

1. The power traces, consisting of the GND trace, the SW trace and the V

2. Does the V

the (+) plate of C

3. Does the (+) plate of CIN connect to V

power MOSFETs.

4. Keep the switching node, SW, away from the sensitive V

5. Keep the (-) plates of C
