HV9120NG-G Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the high-voltage traces short and away from sensitive analog signals. Use a common ground point for the input and output stages.
  • Use a soft-start circuit to limit the inrush current during startup. For shutdown, use a controlled shutdown sequence to prevent voltage spikes and ensure a safe shutdown.
  • The HV9120NG-G has a high power density, so thermal management is crucial. Use a heat sink with a thermal resistance of <1°C/W, and ensure good airflow around the device. Monitor the junction temperature (TJ) and adjust the heat sink design accordingly.
  • Use a low-ESR output capacitor (e.g., ceramic or film capacitor) and optimize the output filter design. Add a snubber circuit to reduce voltage ringing and overshoot. Adjust the output voltage feedback resistors to minimize ripple.
  • Use a shielded enclosure and ensure good grounding. Add EMI filters (e.g., common-mode chokes) to reduce conducted emissions. Use a spread-spectrum clock generator to reduce radiated emissions. Follow good PCB layout practices to minimize radiation.
