NCP3136MNTXG Frequently Asked Questions (FAQs)

  • A 2-layer or 4-layer PCB with a solid ground plane and thermal vias under the IC is recommended. This helps to dissipate heat efficiently and reduce thermal resistance.
  • Ensure that the input voltage rises and falls monotonically, and add a soft-start circuit to limit the inrush current during start-up. Also, add a voltage supervisor to ensure the converter is fully enabled only after the input voltage has reached a minimum threshold.
  • The maximum allowed capacitance is dependent on the specific application and output voltage. As a general guideline, keep the output capacitance below 100uF to avoid stability issues. Consult the datasheet and application notes for more information.
  • Use the datasheet's recommended compensation network values as a starting point, and then adjust the values based on the specific application's requirements and stability analysis. You can also use simulation tools or consult with onsemi's application engineers for guidance.
  • A low-ESR ceramic or film capacitor with a value between 10uF to 22uF is recommended. The capacitor should be rated for the input voltage and have a low equivalent series resistance (ESR) to minimize voltage ripple and noise.
