Texas Instruments provides a recommended PCB layout in the application note SLUA689, which includes guidelines for component placement, trace 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 frequency. Texas Instruments provides a transformer selection guide in the application note SLUA690, which includes guidelines for calculating the transformer's turns ratio, inductance, and core size.
The UCC28517DWR has an operating temperature range of -40°C to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. It's essential to ensure proper thermal management and heat sinking to prevent overheating and ensure reliable operation.
The UCC28517DWR does not have built-in OVP, but it can be implemented using external components, such as a voltage supervisor or a dedicated OVP IC. Texas Instruments provides an example circuit in the application note SLUA691, which includes a voltage supervisor and a reset circuit to protect the device from overvoltage conditions.
The recommended input capacitor value and type depend on the specific application requirements, such as input voltage, frequency, and ripple current. A general guideline is to use a low-ESR ceramic capacitor with a value of 10uF to 22uF, but it's essential to consult the datasheet and application notes for specific recommendations.
