NCP81239MNTXG 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 junction temperature (TJ) should not exceed 150°C to ensure reliable operation.
  • The output voltage ripple can be calculated using the formula: ΔVout = (Iout * Rcoil * fsw) / (L * Cout), where Iout is the output current, Rcoil is the coil resistance, fsw is the switching frequency, L is the inductor value, and Cout is the output capacitance.
