PCB Layout Guide
PCB layout is very important to achieve stable 3) Ensure all feedback connections are short and operation. It is highly recommended to duplicate direct. Place the feedback resistors and EVB layout for optimum performance. If ch ange is compensation components as close t o the chip as necessary, please follow these guidelines and take possible. Figure 4 for reference. 4) VOUT, S W away from sensitive analog areas 1) Keep the path of switching c urrent short and such as FB . minimize the loop area formed by Input capacitor, 5) Connect I high-side MOSFET and low-side MOSFET. N, SW, and especially GND respectively to a large copper area to cool the chip to improve 2) Bypass ceramic capacitors are suggested to be thermal performance and long-term reliability. put close to the Vin Pin. 6) An example of 2-layer PCB layout is shown in Figure 4 for reference.
