25SEK120M Frequently Asked Questions (FAQs)

  • A symmetrical layout with a solid ground plane and a separate power plane is recommended. Keep the high-frequency components away from the power plane and ensure a low-impedance path for the output capacitor.
  • Implement a proper thermal management system, such as a heat sink or a thermal pad, to keep the junction temperature below 125°C. Also, ensure that the device is operated within the recommended operating conditions.
  • A 10uF to 22uF ceramic capacitor with an X7R or X5R dielectric is recommended for input filtering. The capacitor should be placed as close as possible to the VIN pin.
  • Use a shielded enclosure, keep the switching node (SW pin) away from sensitive components, and add a common-mode choke or a ferrite bead to the output cable. Also, ensure that the PCB layout is optimized for EMI reduction.
  • The maximum allowed output capacitance is 220uF. Exceeding this value may cause instability or oscillations in the output voltage.
