VIPER35HD Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a 4-layer PCB with a solid ground plane, and a separate layer for the high-voltage power supply. The layout should also minimize the loop area of the high-frequency current paths to reduce EMI.
  • To ensure reliable start-up, make sure the input voltage is within the recommended range, and the input capacitor is properly sized. Also, ensure that the soft-start capacitor is correctly sized and the soft-start time is sufficient to allow the IC to start up smoothly.
  • The maximum allowed voltage on the VCC pin is 28V, but it's recommended to keep it below 25V to ensure reliable operation and to prevent damage to the IC.
  • Choose a transformer with a turns ratio that matches the input and output voltage requirements of your design. Ensure the transformer is designed for high-frequency operation (e.g., 65 kHz) and has a suitable power rating. Consult the transformer manufacturer's datasheet and application notes for guidance.
  • Ensure good thermal conductivity between the IC and the PCB, and consider using a heat sink or thermal pad to dissipate heat. Keep the IC away from other heat sources, and ensure good airflow around the device. Monitor the junction temperature (TJ) to prevent overheating.
