VIPER20(022Y) datasheet by STMicroelectronics

VIPER20(022Y) Frequently Asked Questions (FAQs)

• What is the maximum operating temperature range for VIPER20(022Y)?
  The maximum operating temperature range for VIPER20(022Y) is -40°C to 150°C.
• How do I ensure the VIPER20(022Y) is properly cooled?
  To ensure proper cooling, make sure to provide a heat sink with a thermal resistance of less than 10°C/W and ensure good airflow around the device.
• What is the recommended PCB layout for VIPER20(022Y) to minimize EMI?
  To minimize EMI, use a multi-layer PCB with a solid ground plane, keep the layout symmetrical, and use a shielded transformer. Also, keep the high-frequency components away from the low-frequency components.
• How do I select the right transformer for VIPER20(022Y)?
  Select a transformer with a turns ratio that matches the input and output voltage requirements, and ensure the transformer's saturation current is higher than the peak current of the VIPER20(022Y).
• What is the recommended input capacitor value for VIPER20(022Y)?
  The recommended input capacitor value is 1-10uF, depending on the input voltage and current requirements. A higher capacitance value can help reduce input voltage ripple.
