MC34063ABN Frequently Asked Questions (FAQs)

  • The maximum input voltage is 40V, but it's recommended to keep it below 35V 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, inductor value, and switching frequency. A good starting point is to use the value recommended in the datasheet (typically 10nF to 100nF).
  • The operating frequency range is typically between 100kHz to 500kHz. To ensure the device operates within this range, choose the correct values for the oscillator resistors (Rt and Ct) and the inductor value. The datasheet provides a formula to calculate the oscillator frequency.
  • The maximum output current depends on the input voltage, output voltage, and inductor value. Typically, the MC34063ABN can deliver up to 1.5A, but it's recommended to derate the output current based on the ambient temperature and input voltage.
