VIPER50-E datasheet by STMicroelectronics

VIPER50-E Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for the VIPER50-E?
  The maximum operating temperature range for the VIPER50-E is -40°C to 150°C, but it can be derated to 125°C for high-reliability applications.
• How do I ensure the VIPER50-E is properly cooled?
  Proper cooling can be achieved by using a heat sink with a thermal resistance of less than 10°C/W, and ensuring good airflow around the device. The PCB layout should also be designed to minimize thermal resistance.
• What is the recommended input capacitor value for the VIPER50-E?
  The recommended input capacitor value for the VIPER50-E is 10nF to 100nF, depending on the input voltage and frequency. A larger capacitor value can help reduce input voltage ripple.
• How do I prevent electromagnetic interference (EMI) with the VIPER50-E?
  To prevent EMI, use a shielded transformer, keep the PCB layout compact, and use a common-mode choke or EMI filter on the input and output lines. Additionally, ensure good grounding and decoupling of the device.
• What is the maximum output power rating for the VIPER50-E?
  The maximum output power rating for the VIPER50-E is 50W, but it can be derated based on the input voltage, output voltage, and operating temperature.
