UCC2895DW Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane, and placing the UCC2895DW close to the input capacitors and output inductors. Additionally, keep the high-frequency components (e.g., switching node, bootstrap capacitor) away from sensitive analog circuits.
  • Use TI's WEBENCH Power Designer tool or manual calculations to determine the optimal compensation network values. Ensure the compensation network is properly tuned for the specific application's operating conditions and component values.
  • Choose capacitors with low ESR, high ripple current rating, and suitable voltage ratings. Ensure the input capacitor can handle the input voltage and ripple current, and the output capacitor can handle the output voltage and ripple current.
  • Set the OCP threshold (Rocp) according to the application's requirements. Ensure the OCP pin is properly connected to a resistor divider network, and the OCP threshold is set below the maximum allowed current to prevent damage to the device.
  • Ensure good thermal conduction between the device and the PCB. Use thermal vias, thermal pads, or a heat sink to dissipate heat. Monitor the device's junction temperature (TJ) and ensure it remains within the recommended operating range (TJ < 150°C).
