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. STMicroelectronics provides a transformer selection guide in the datasheet, and engineers can also use online tools, such as the STMicroelectronics Transformer Selector, to find a suitable transformer.
The VIPER12AS13TR has a high power density, and thermal management is crucial. Engineers should 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.
The VIPER12AS13TR has built-in OVP and UVP features, but engineers can also implement external protection circuits using resistors, zener diodes, and comparators. The application note AN4571 provides examples of OVP and UVP circuits.
The VIPER12AS13TR is a switching converter, and EMI filtering is essential to meet regulatory requirements. Engineers should use a combination of input and output filters, such as LC filters, to reduce EMI emissions. The application note AN4571 provides guidance on EMI filtering.
