Layout Guidelines for Switching Power Supplies (from National Semiconductor AN-1149) When laying out a circuit (of any kind) parts placement is important. This is especially important for switching power supplies. Problems associated with layout are most often evident with: High current levels Large differentials in input/output voltageTo suppress noise produced when switching the power supply, place a grounded bypass capacitor close to the supply pin of the operational amplifier. The bypass capacitor should have a short path between the op-amps power pin and the ground connection. A bypass capacitor will ensure the operational amplifier produces the correct output.AC/DC Switch Mode Power Supply Design Guide Fairchild is the only semiconductor supplier that provides a complete portfolio for AC/DC switch mode power supplies.
