BQ4802LYPWR Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the input and output capacitors close to the IC, and use short, wide traces for the power lines.
  • Use a thermal pad or a heat sink to dissipate heat. Ensure good airflow around the device, and avoid blocking the thermal pad. Monitor the junction temperature (TJ) and adjust the design accordingly.
  • A 10uF to 22uF X5R or X7R ceramic capacitor is recommended, placed as close to the VIN pin as possible. This helps to filter the input voltage and reduce noise.
  • Choose an output capacitor with low ESR (Equivalent Series Resistance) and a capacitance value between 10uF to 47uF. A 22uF X5R or X7R ceramic capacitor is a good starting point. Consider the output voltage ripple and transient response requirements.
  • The BQ4802LYPWR operates at a fixed frequency of 2.2 MHz. This frequency is optimized for efficiency and is not adjustable.
