BQ24707RGRR Frequently Asked Questions (FAQ)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-current paths is recommended. Ensure that the input and output capacitors are placed close to the IC, and the inductor is placed near the IC's switching node.

  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-2.2 μH). Consider the inductor's physical size, core material, and operating frequency when selecting the optimal inductor.

  • Use a low-ESR, high-frequency ceramic capacitor (e.g., X5R or X7R) with a value between 4.7 μF to 10 μF. Ensure the capacitor is rated for the input voltage and has a low impedance at the switching frequency.

  • 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 based on the desired output voltage and the internal reference voltage (0.8 V).

  • The maximum ambient temperature for the BQ24707RGRR is 85°C. Ensure proper thermal design and heat dissipation to maintain a safe operating temperature.
