STMicroelectronics provides a recommended PCB layout in the application note AN4392, which includes guidelines for component placement, routing, and thermal management to ensure optimal performance and minimize electromagnetic interference (EMI).
The selection of the transformer depends on the specific application requirements, such as output power, voltage, and current. STMicroelectronics provides a transformer selection guide in the application note AN4392, which includes a list of recommended transformers and their characteristics.
The TEA3718SP is rated for operation in an ambient temperature range of -40°C to +125°C, but the maximum ambient temperature range may be limited by the specific application and the thermal management system used.
To ensure EMC, follow the guidelines in the application note AN4392, which includes recommendations for PCB layout, component selection, and shielding. Additionally, perform EMC testing and certification according to relevant standards, such as IEC 61000-4-2 and IEC 61000-4-4.
The typical efficiency of the TEA3718SP is around 85-90% at full load, depending on the specific application and operating conditions. However, the actual efficiency may vary depending on the design and implementation of the power supply.
