BQ29702DSER Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate layer for the high-voltage traces is recommended. Keep the high-voltage traces short and away from the low-voltage traces. Use a common ground point for the IC and the external components.
  • Choose components with a voltage rating higher than the maximum input voltage. Select capacitors with low ESR and a high ripple current rating. The inductor should have a high saturation current and low DCR. Refer to the datasheet for specific component recommendations.
  • The EN (enable) pin is used to turn the device on and off. Connect EN to a logic-level input (e.g., a microcontroller output) to control the device's operation. A high level on EN enables the device, while a low level disables it.
  • The output voltage is adjusted by selecting the appropriate resistors for the feedback network (RFBT and RFB). Use the formula provided in the datasheet to calculate the required resistor values for the desired output voltage.
  • The device has a thermal shutdown feature that turns it off when the junction temperature exceeds 150°C. Ensure good airflow, use a heat sink if necessary, and follow the recommended PCB layout to minimize thermal resistance.
