STMicroelectronics provides a recommended PCB layout in the application note AN4571, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and reliability.
The transformer selection depends on the input voltage, output voltage, and power rating. STMicroelectronics provides a transformer selection guide in the datasheet, and also recommends using their online transformer selection tool to find the optimal transformer for your design.
The VIPER12ASTR-E has a high power density, so thermal management is crucial. Ensure good airflow, use a heat sink if necessary, and follow the thermal design guidelines in the datasheet to keep the junction temperature below 150°C.
Follow the EMC guidelines in the datasheet, use a shielded transformer, and ensure proper PCB layout and routing to minimize electromagnetic interference. Additionally, use EMI filters and shielding if necessary to meet the required EMC standards.
Ensure the device is used within the recommended operating conditions, follow the safety guidelines in the datasheet, and use protective components such as fuses and varistors to prevent overvoltage and overcurrent conditions.
