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 specific application requirements, such as output voltage, current, and power rating. STMicroelectronics provides a transformer selection guide in the datasheet, and also recommends using transformers from approved vendors, such as TDK, Coilcraft, or Würth Elektronik.
VIPER35LDTR has a high power density, and thermal management is critical to ensure reliable operation. The device has an exposed pad for heat sinking, and STMicroelectronics recommends using a thermal interface material (TIM) and a heat sink to keep the junction temperature below 150°C.
VIPER35LDTR has a built-in OVP feature, but it can be adjusted or disabled using external resistors. STMicroelectronics provides guidelines for OVP implementation in the datasheet, and also recommends using a dedicated OVP IC, such as the STM662, for more advanced protection features.
VIPER35LDTR is designed to meet EMI standards, but proper PCB layout, component selection, and shielding are still necessary to minimize EMI. STMicroelectronics provides EMI guidelines in the application note AN4571, and recommends using EMI filters, such as the STM671, to further reduce EMI emissions.
