NB681GD-Z Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power lines.
  • Ensure that the output capacitor has a low ESR, and the input capacitor has a high capacitance. Also, add a 10nF-100nF capacitor between the VIN and GND pins to filter out noise.
  • Although the datasheet specifies a maximum input voltage of 18V, it's recommended to limit the input voltage to 15V to ensure reliable operation and prevent overheating.
  • The output voltage ripple can be estimated using the formula: ΔVout = (Iout * ESR) / (f * Cout), where Iout is the output current, ESR is the output capacitor's equivalent series resistance, f is the switching frequency, and Cout is the output capacitance.
  • A 10uF-22uF X5R or X7R ceramic capacitor is recommended for the input capacitor. This type of capacitor provides a low ESR and is suitable for high-frequency switching applications.
