4 / 13 page Recommended PCB Iayout AN3302 4/13 Doc ID 18163 Rev 1 2 Recommended PCB Iayout 2.1 Layout considerations The layout is an important design step for all switching power supplies due to the high switching frequency and peak current. If the layout is not performed carefully, important parameters such as efficiency and output voltage ripple may be out of specification. Short, wide traces must be implemented for the main current and for power ground paths. The input capacitor must be placed as close as possible to the IO pins as well as the inductor and output capacitor. The feedback pin (FB) connection to the external resistor divider is a high impedance node, so interference can be minimized by placing the routing of the feedback node as far as possible from the high current paths. To reduce pick-up noise, the resistor divider must be placed very close to the device. A common ground node minimizes ground noise. The exposed pad of the package must be connected to the common ground node. Figure 3. Recommended PCB layout AM07857v1 AM07857v1 |
