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 LTC2945'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.
