LTC2946HDE#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., 1 mΩ) and place it close to the IC. Ensure the sense resistor is in the same thermal zone as the IC to minimize temperature differences.
  • The maximum ambient temperature for the LTC2946HDE is 105°C. However, the device can operate up to 125°C with derating. Consult the datasheet for thermal derating curves.
  • The LTC2946HDE is designed for 3.3V or 5V input voltage. While it may be possible to use it with other input voltages, this is not recommended and may affect performance and accuracy.
  • Calibration is not required for the LTC2946HDE, as it is a ratiometric device. However, ensure that the input voltage and current sense resistor values are accurate and within the recommended ranges.
