STMicroelectronics provides a recommended PCB layout in the application note AN4571, which includes guidelines for component placement, thermal management, and routing to minimize electromagnetic interference (EMI) and ensure reliable operation.
The transformer selection depends on the input voltage, output voltage, and power rating of the application. STMicroelectronics provides a transformer selection guide in the datasheet, and also recommends using transformers from approved vendors, such as TDK, Coilcraft, or Würth Elektronik.
The maximum junction temperature (Tj) of VIPER20ADIP is 150°C, but it's recommended to keep the junction temperature below 125°C for reliable operation and to ensure a long lifespan.
Yes, VIPER20ADIP is suitable for high-reliability and safety-critical applications, such as industrial, medical, and automotive systems. It meets the requirements of various industry standards, including IEC 61508, IEC 62368, and ISO 26262.
To ensure EMC, follow the guidelines in the application note AN4571, which includes recommendations for PCB layout, component selection, and shielding. Additionally, use a common-mode choke and a Y-capacitor to filter out electromagnetic interference (EMI).
