UC3914N Frequently Asked Questions (FAQ)

  • TI recommends a compact layout with short traces, and placing the IC close to the input capacitors. Additionally, a solid ground plane and a shielded enclosure can help reduce EMI and noise.

  • To ensure stability, ensure the input and output capacitors are properly sized and placed, and the feedback resistors are correctly chosen. Also, avoid using long feedback traces and keep the loop gain below 1 at the oscillation frequency.

  • The UC3914N can handle input voltages up to 40V, but it's recommended to keep the input voltage below 30V to ensure reliable operation and prevent damage to the IC.

  • The UC3914N is rated for operation up to 125°C, but it's recommended to derate the output power and ensure proper heat sinking to prevent overheating and reduce reliability.

  • Check the input voltage, output voltage, and current sense resistors for proper connection and values. Verify the feedback loop is properly connected and the compensation components are correct. Also, check for overheating, and ensure the IC is properly soldered and mounted.
