STMicroelectronics provides a recommended PCB layout in the application note AN4985, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and reliability of the VIPER50SP.
The selection of the transformer depends on the specific application requirements, such as output power, voltage, and frequency. STMicroelectronics provides a transformer selection guide in the application note AN4985, which includes a list of recommended transformers and their characteristics.
The VIPER50SP has a high power density, and thermal management is critical to ensure reliable operation. The device has a thermal pad that must be connected to a heat sink or a thermal interface material to dissipate heat. The application note AN4985 provides guidelines for thermal management, including thermal pad connection and heat sink design.
The VIPER50SP has a built-in OVP feature that can be enabled by connecting the OVP pin to a voltage divider network. The application note AN4985 provides a detailed example of how to implement OVP, including the calculation of the voltage divider resistors and the OVP threshold voltage.
The VIPER50SP is a high-frequency switching converter, and EMI can be a concern. STMicroelectronics provides guidelines for EMI reduction in the application note AN4985, including the use of shielding, filtering, and layout techniques to minimize EMI radiation.
