BQ24773RUYR 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.
  • The BQ24773RUYR is rated for operation up to 105°C, but it's essential to ensure proper thermal management, such as using a heat sink or thermal interface material, to maintain a safe junction temperature.
  • Consult the troubleshooting guide in the datasheet or application note (SLUA623). Common issues include incorrect compensation network values, inadequate PCB layout, or insufficient input capacitance.
