BQ25898YFFT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the power traces is recommended. Keep the input and output capacitors close to the IC and use short, wide traces for the power paths.
  • Use a thermal pad or a heat sink to dissipate heat. Ensure good airflow around the device and avoid blocking the airflow. Monitor the junction temperature (TJ) and adjust the design as needed to keep TJ below 125°C.
  • A low-ESR ceramic capacitor (X5R or X7R) with a value of 10-22 μF is recommended. The capacitor should be placed close to the VIN pin and have a low inductance path to the IC.
  • Use the FB pin to set the output voltage. Connect a resistive divider from the output voltage to the FB pin, and calculate the resistor values using the formula provided in the datasheet.
  • The BQ25898YFFT can handle input voltages up to 18V, but it's recommended to keep the input voltage below 15V for optimal performance and reliability.
