LTC4267IGN#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 thermal pad or thermal interface material to improve heat transfer between the IC and the PCB. Ensure good airflow around the IC, and consider using a heat sink if the device will be operating at high currents or in high-temperature environments.
  • A low-ESR ceramic capacitor with a value of 10uF to 22uF is recommended. The capacitor should be placed close to the VIN pin and have a voltage rating of at least 2x the maximum input voltage.
  • The output voltage can be adjusted by changing the ratio of the resistors R1 and R2 in the feedback network. Use the formula VOUT = 0.8V x (1 + R2/R1) to calculate the desired resistor values.
  • The maximum input voltage is 36V, but the device can withstand up to 40V for short periods of time. However, operating the device at voltages above 36V for extended periods may reduce its reliability.
