BQ24780SRUYR 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 high-current paths are routed away from sensitive analog signals.
  • Use the provided compensation network calculation tool or consult the application note (SLUA623) for guidance. The compensation network values depend on the specific application, output voltage, and inductor value.
  • The maximum input voltage rating is 24V, but it's recommended to operate within 18V to ensure reliable operation and minimize stress on the internal components.
  • Yes, the BQ24780SRUYR supports synchronous rectification. Connect the SR pin to the drain of the synchronous rectifier MOSFET, and ensure the MOSFET is properly sized for the application.
  • Use a thermal pad or a heat sink to dissipate heat. Ensure good airflow, and consider using a thermal interface material (TIM) to improve heat transfer. Monitor the junction temperature (TJ) and adjust the design accordingly.
