NCP81296MNTXG 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 rises monotonically and does not droop during start-up. A soft-start circuit can be used to limit the inrush current and ensure reliable start-up.
  • The maximum allowed voltage on the EN pin is 6V. Exceeding this voltage may damage the device.
  • Yes, the device is rated for operation up to 150°C. However, the maximum operating temperature may be limited by the specific application and PCB design.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * Rl) / (fsw * Cout), where Rl is the load resistance, fsw is the switching frequency, and Cout is the output capacitance.
