10 Layout

10.1 Layout Guidelines

  • For all switching power supplies, the layout is an important step in the design, especially at high peak currents and switching frequencies. If the layout is not carefully done, the regulator shows stability problems as well as EMI problems.
  • Therefore use wide and short traces for the main current paths, as indicated in bold in Figure 19. The input capacitor should be placed as close as possible to the IC pins.
  • The feedback resistor network must be routed away from the inductor and switch node to minimize noise and magnetic interference. To further minimize noise from coupling into the feedback network and feedback pin, the ground plane or ground traces must be used for shielding. This becomes very important especially at high switching frequencies of 1 MHz.
