VIPER26HD 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 circuits to reduce EMI.
  • To ensure the VIPER26HD operates within its SOA, monitor the device's junction temperature, output current, and input voltage. Use thermal management techniques, such as heat sinks or thermal interfaces, to keep the junction temperature below 150°C.
  • When selecting a transformer for the VIPER26HD, consider the transformer's turns ratio, inductance, and core material. Ensure the transformer is designed for high-frequency operation and can handle the required power levels.
  • Optimize the output filter by selecting the right component values and layout to minimize EMI. Use a common-mode choke and a differential-mode filter to reduce conducted EMI. Ensure the filter is designed to meet the required attenuation levels for regulatory compliance.
  • Use a combination of oscilloscopes, signal generators, and power analyzers to verify the VIPER26HD's performance. Measure the output voltage, current, and power factor to ensure the device is operating within its specifications.
