NCP1090DBRG Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias is recommended. Keep the component side of the PCB clear of copper to minimize thermal resistance.
  • Ensure that the input voltage is within the specified range, and the output capacitor is properly sized to handle the inrush current. Also, add a soft-start circuit to limit the inrush current.
  • The maximum allowed capacitance on the output is 220uF. Exceeding this value may cause instability or oscillations in the converter.
  • While the datasheet recommends a specific inductor value and type, you can use a different one as long as it meets the specified inductance, DC resistance, and saturation current requirements.
  • Check the PCB layout, component values, and soldering quality. Ensure that the input and output capacitors are properly sized and placed. Also, verify that the inductor is not saturating.
