MC34063AP Frequently Asked Questions (FAQ)

  • 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, output current, and the type of output capacitor used. A good starting point is to use a value between 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 timing resistor (Rt) and capacitor (Ct) according to the datasheet or use online calculators.

  • The maximum output current is 1.5A, but it's recommended to derate the output current based on the input voltage, output voltage, and ambient temperature to ensure reliable operation.
