A good PCB layout for the LT6703HDC-2 involves keeping the input and output capacitors close to the IC, using a solid ground plane, and minimizing trace lengths and widths to reduce parasitic inductance and capacitance.
To ensure stability, ensure that the output capacitor is properly sized, the input voltage is within the recommended range, and the feedback resistors are properly selected. Additionally, adding a small capacitor (e.g., 10nF) between the output and ground can help prevent oscillations.
The LT6703HDC-2 can deliver up to 3A of output current, but this may be limited by the thermal performance of the package and the PCB design. Be sure to check the thermal derating curves in the datasheet to ensure reliable operation.
The LT6703HDC-2 is rated for operation up to 125°C, but the maximum junction temperature (TJ) should not exceed 150°C. Be sure to check the thermal derating curves in the datasheet and ensure proper heat sinking and airflow to prevent overheating.
Choose input capacitors with low ESR (equivalent series resistance) and high ripple current capability. Output capacitors should have low ESR and be rated for the maximum output voltage. Consult the datasheet for recommended capacitor values and types.
