UCC3801N Frequently Asked Questions (FAQ)

  • TI recommends a compact layout with the UCC3801N placed close to the transformer, and the use of a ground plane to minimize EMI and noise. Additionally, TI provides a reference design and layout guidelines in the application notes.

  • The transformer selection depends on the specific application requirements, such as output power, voltage, and frequency. TI provides a transformer selection guide and recommendations in the application notes and datasheet.

  • The UCC3801N has a high power density, so thermal management is critical. TI recommends using a heat sink with a thermal resistance of <1°C/W, and ensuring good airflow around the device. Additionally, the PCB layout should be designed to minimize thermal resistance.

  • The UCC3801N has a built-in overcurrent protection feature, but additional fault detection and protection circuits may be required depending on the application. TI provides guidelines and examples in the application notes and datasheet.

  • The UCC3801N requires input and output filtering to meet EMI and noise requirements. TI recommends using a pi-filter or a common-mode choke on the input, and a LC filter on the output. The specific filter requirements depend on the application and regulatory requirements.
