PCB LAYOUT GUIDE
PCB layout is very important to achieve stable
operation. It is highly recommended to duplicate
EVB layout for optimum performance.
1) If change is necessary, please follow these
guidelines and take Figure 6 for reference.
2) Keep the path of switching current short and
minimize the loop area formed by Input cap,
high-side MOSFET and external switching
diode.
3) Bypass ceramic capacitors are suggested to
be put close to the VIN Pin.
4) Ensure all feedback connections are short
and direct. Place the feedback resistors and
compensation components as close to the
chip as possible.
5) Route SW away from sensitive analog areas
such as FB.
6) Connect IN, SW, and especially GND
respectively to a large copper area to cool
the chip to improve thermal performance and
long-term reliability.
