BQ24735RGRR Frequently Asked Questions (FAQs)

  • 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 close to the output capacitors.
  • Choose an inductor with a high saturation current rating, low DC resistance, and a suitable inductance value (e.g., 1-10 μH). Consider the inductor's physical size, core material, and operating frequency when making your selection.
  • The maximum input voltage is 18V, but it's recommended to keep the input voltage below 15V to ensure reliable operation and minimize power losses.
  • The soft-start feature is enabled by connecting the SS pin to a capacitor (e.g., 10 nF) and a resistor (e.g., 10 kΩ) in series. The capacitor value determines the soft-start time, and the resistor value sets the soft-start current limit.
  • The EN (enable) pin is used to turn the converter on and off. Connect the EN pin to a logic signal (e.g., from a microcontroller) to enable or disable the converter. A high logic level (e.g., 3.3V) enables the converter, while a low logic level (e.g., 0V) disables it.
