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 VIPER100A. STMicroelectronics provides a transformer selection guide in the datasheet, and engineers can also use online tools or consult with transformer manufacturers to find a suitable transformer.
The VIPER100A has a high power density, and thermal management is critical to ensure reliable operation. Engineers should consider using a heat sink, thermal interface material, and ensuring good airflow around the device. The application note AN4571 provides more detailed guidelines on thermal management.
The VIPER100A has built-in OVP and UVP features, but engineers can also implement external OVP and UVP circuits using resistors, zener diodes, and comparators. The application note AN4571 provides examples of external OVP and UVP circuits.
The VIPER100A is a switching converter, and EMI is a concern. Engineers should consider using EMI filters, shielding, and proper PCB layout to minimize EMI. The application note AN4571 provides guidelines on EMI reduction techniques.
