MC33063AD Frequently Asked Questions (FAQs)

  • The MC33063AD can handle input voltages up to 40V, but it's recommended to keep it below 35V for reliable operation.
  • The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific application requirements.
  • The bootstrap capacitor (CBOOT) is used to generate the high-side gate drive voltage. The recommended value is 10nF to 22nF, but it may need to be adjusted based on the specific application requirements and the value of the high-side FET.
  • Ensure good thermal design and heat sinking, especially for high-power applications. Use a thermal pad or heat sink to dissipate heat, and consider using a thermistor or thermal sensor to monitor the temperature.
  • Keep the high-current paths short and wide, use a solid ground plane, and separate the high-frequency and low-frequency circuits. Also, ensure good decoupling and bypassing of the power supply lines.
