UCC2801D Frequently Asked Questions (FAQs)

  • The UCC2801D is a high-frequency device, so it's crucial to follow good PCB layout practices to minimize noise and EMI. Place the device close to the power stage, use a solid ground plane, and keep the high-current paths short and wide. TI provides a recommended layout in the datasheet and application notes.
  • The choice of external components, such as the bootstrap capacitor, current sense resistor, and output filter components, depends on the specific application requirements. TI provides guidelines and equations in the datasheet to help select the right components. Additionally, the TI Power Stage Designer tool can aid in component selection.
  • The maximum allowed voltage on the VCC pin is 15V, but it's recommended to keep it below 12V for reliable operation. Exceeding this voltage can damage the device.
  • The UCC2801D has a built-in overcurrent protection feature. Connect a current sense resistor (RCS) between the source of the low-side FET and ground. The device will detect overcurrent conditions and shut down if the current exceeds the threshold set by the RCS value.
  • Yes, the UCC2801D is suitable for synchronous rectification topologies. The device's adaptive non-overlap time (ANOT) feature helps to minimize dead time and reduce power losses in synchronous rectification applications.
