LTC2946CMS#PBF Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the high-current paths.
  • Use a low-impedance current sense resistor (e.g., 1mΩ) and place it close to the IC. Ensure the sense resistor is in the same thermal zone as the IC to minimize temperature-related errors.
  • The maximum allowed voltage drop is 50mV. Exceeding this may cause inaccurate current measurements or damage to the IC.
  • Yes, but ensure the switching frequency is above 100kHz to avoid interference with the LTC2946's internal oscillator. Also, use a low-ESR output capacitor to minimize ripple and noise.
  • Use a precision voltage source and a calibrated current source to calibrate the IC. Follow the calibration procedure outlined in the datasheet, and ensure the IC is in a stable thermal environment.
