BQ24314ADSGR Frequently Asked Questions (FAQ)

  • 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 power paths. Avoid routing sensitive analog signals near the switching node.

  • The inductor value depends on the input voltage, output voltage, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet. Then, adjust the value based on the specific application requirements and efficiency targets.

  • The BQ24314ADSGR is rated for operation from -40°C to 125°C. However, the maximum ambient temperature range may be limited by the specific application and the thermal design of the system.

  • Yes, the BQ24314ADSGR is AEC-Q100 qualified and suitable for high-reliability and automotive applications. However, additional testing and validation may be required to meet specific industry standards and regulations.

  • Use an oscilloscope to monitor the input and output voltages, as well as the switching node. Check for proper PCB layout, component selection, and thermal design. Consult the datasheet and application notes for troubleshooting guidelines and common pitfalls to avoid.
