VIPER12AS-E Frequently Asked Questions (FAQs)

  • STMicroelectronics recommends a 4-layer PCB with a solid ground plane, and a separate layer for the high-voltage traces. The datasheet provides a recommended PCB layout, but it's essential to follow good PCB design practices to minimize electromagnetic interference (EMI) and ensure reliable operation.
  • The transformer selection depends on the output power, voltage, and current requirements. STMicroelectronics provides a transformer selection guide in the datasheet, but it's crucial to consider factors like core material, turns ratio, and leakage inductance to ensure efficient energy transfer and minimize losses.
  • The VIPER12AS-E has a maximum junction temperature of 150°C. Ensure good thermal conductivity by using a heat sink, thermal interface material, and a well-designed PCB with adequate copper thickness. Keep the device away from heat sources, and consider using a thermal shield or potting compound for high-reliability applications.
  • The VIPER12AS-E has a built-in OVP feature, but it's essential to add external components to ensure reliable operation. Use a voltage supervisor or a dedicated OVP IC to monitor the output voltage and shut down the device in case of an overvoltage event. Add a zener diode or a TVS diode to clamp the voltage and protect the device from voltage spikes.
  • To minimize EMI, use a shielded transformer, keep the high-voltage traces short and away from sensitive circuits, and add EMI filters or common-mode chokes as needed. Ensure good PCB layout practices, and consider using a metal enclosure or shielding to contain EMI radiation.
