STMicroelectronics provides a recommended PCB layout in the VIPER28HD evaluation board documentation, which includes guidelines for component placement, thermal management, and routing. Following this layout can help ensure optimal performance and minimize electromagnetic interference (EMI).
The transformer selection depends on the input voltage, output voltage, and power rating of the VIPER28HD. STMicroelectronics provides a transformer selection guide in the datasheet, which includes formulas and tables to help engineers choose the right transformer. Additionally, STMicroelectronics offers a range of recommended transformers that are compatible with the VIPER28HD.
The VIPER28HD has a high power density, which requires proper thermal management to ensure reliable operation. Engineers should consider using a heat sink, thermal interface material, and a well-designed PCB layout to dissipate heat. STMicroelectronics provides thermal management guidelines in the datasheet and application notes.
The VIPER28HD has built-in OVP and UVP features, but engineers need to implement external circuitry to detect and respond to voltage faults. STMicroelectronics provides application notes and design examples that demonstrate how to implement OVP and UVP using external components and the VIPER28HD's fault detection pins.
The VIPER28HD is designed to meet EMC standards, but engineers should still consider EMC during the design and layout phase. This includes using shielding, filtering, and proper grounding to minimize electromagnetic interference (EMI). STMicroelectronics provides EMC guidelines and application notes to help engineers design EMC-compliant systems.
