UC2708DW Frequently Asked Questions (FAQs)

  • TI recommends a 4-layer PCB with a solid ground plane, and a separate power plane for the high-current output stage. Keep the input and output stages separate, and use a Kelvin connection for the output sense resistors. Refer to the TI application note SLUA271 for more details.
  • Use a soft-start circuit to limit the inrush current during startup, and a shutdown circuit to discharge the output capacitors. TI recommends a resistive divider network to control the startup and shutdown sequence. Refer to the TI application note SLUA272 for more details.
  • The UC2708DW can deliver up to 8A of output current, but this depends on the specific application, PCB design, and thermal management. TI recommends derating the output current based on the ambient temperature and the device's thermal performance.
  • Use a type-2 compensation network, which includes a zero and a pole, to stabilize the output voltage. TI recommends using a 1kΩ resistor and a 10nF capacitor for the compensation network. Refer to the TI application note SLUA273 for more details.
  • Use a low-ESR, high-frequency ceramic capacitor (e.g., X7R or X5R) with a value of 10uF to 22uF. This helps to filter the input voltage and reduce noise.
