BQ24401D 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.
  • Choose an inductor with a value between 1.5uH to 3.3uH, depending on the input voltage, output voltage, and desired switching frequency. Use the TI SwitcherPro software or a similar tool to simulate and optimize the design.
  • The maximum ambient temperature for the BQ24401D is 85°C. However, the device can operate up to 125°C junction temperature, but with derated performance.
  • Yes, the BQ24401D can be used in a synchronous rectification configuration to improve efficiency. However, this requires additional external components and careful PCB layout to minimize parasitic inductance.
  • Use an oscilloscope to monitor the input and output voltages, as well as the switch node voltage. Check for proper PCB layout, component selection, and thermal management. Consult the TI application notes and technical support resources for guidance.
