MC34063EBD Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the MC34063EBD is 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 it based on the specific requirements of your application.
  • The bootstrap capacitor (CBOOT) is used to provide a high-voltage supply to the internal switch driver. The recommended value is 10nF to 100nF, but it can be adjusted based on the specific requirements of your application.
  • To ensure stable operation in a high-temperature environment, make sure to follow the recommended operating conditions, use a suitable heat sink, and consider using a thermistor to monitor the temperature and adjust the output voltage accordingly.
  • The maximum output current that the MC34063EBD can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation.
