VIPER20A-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 to minimize noise and EMI. A good layout should also ensure that the input and output capacitors are placed close to the IC.
  • 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 feedback network is properly designed to provide a stable output voltage.
  • 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.
  • Yes, the VIPER20A-E is rated for operation up to 150°C, but it's essential to ensure proper thermal management and heat sinking to prevent overheating and ensure reliable operation.
  • To troubleshoot issues, start by checking the PCB layout, ensuring that the input and output capacitors are properly sized and placed. Also, verify that the feedback network is properly designed and that the input voltage is within the recommended range. If issues persist, consult the STMicroelectronics application notes and technical support resources.
