PCB Considerations
A good PCB design is very important to efficiency and performance.
When laying out the printed circuit board, the following considerations should be taken to ensure proper operationof the IC.
If possible, use multi-layer PCB for better performance.
The ground connections of output capacitor, N-channel MOSFET, and catch diode (D2 in Figure 2)
need to feed into same copper that connects to the input capacitor ground before tying back into system ground.
This copper should be as wide as possible, and back to system ground separately.
To minimize radiation, the 2 diodes, MOSFETs, inductorand the input bypass capacitortraces should be kept as short as possible.
The connection between the diode and the MOSFETs should also be kept as short aspossible.
Place the inductor current sense resistor RCS right next to the input capacitor and inductor but oriented such that the IC’s CSN and VIN traces going to RCS are not long.
The 2traces need to be routed to getheras a single pair on the same layer at any given time with smallest trace spacing possible.
