MC34063ADR Frequently Asked Questions (FAQ)

  • The MC34063ADR can handle input voltages up to 40V, but it's recommended to keep it below 30V for reliable operation.

  • The inductor value depends on the output voltage, current, and switching frequency. A good starting point is to use the inductor selection guide in the datasheet or online calculators. Typically, a value between 10uH to 100uH is suitable for most applications.

  • The compensation capacitor (Cc) is used to stabilize the voltage regulator. The value of Cc depends on the output voltage, output current, and the type of output capacitor used. A good starting point is to use a value between 10nF to 100nF.

  • To ensure the MC34063ADR operates within its SOA, make sure to keep the input voltage, output voltage, and output current within the recommended limits. Also, ensure the device is properly heat-sinked and the PCB is designed to minimize thermal resistance.

  • The MC34063ADR can deliver up to 1.5A of output current, but it's recommended to keep it below 1A for reliable operation.
