MC34063EBD datasheet by STMicroelectronics

MC34063EBD Frequently Asked Questions (FAQs)

• What is the maximum input voltage that can be applied to the MC34063EBD?
  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.
• How do I choose the right inductor value for my application?
  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.
• What is the purpose of the bootstrap capacitor (CBOOT) and how do I choose its value?
  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.
• How do I ensure stable operation of the MC34063EBD in a high-temperature environment?
  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.
• What is the maximum output current that the MC34063EBD can deliver?
  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.
