MC34063ACD Frequently Asked Questions (FAQs)

  • The maximum input voltage that can be applied to the MC34063ACD is 40V, but it's recommended to keep it below 35V for reliable operation.
  • The output voltage of the MC34063ACD can be calculated using the formula: Vout = (R1 / R2) * (Vin - Vsat), where R1 and R2 are the resistors connected to the feedback pin, Vin is the input voltage, and Vsat is the saturation voltage of the internal switch (around 1.5V).
  • The minimum input voltage required for the MC34063ACD to operate is around 3.5V, but it's recommended to keep it above 4.5V for reliable startup and operation.
  • Yes, the MC34063ACD can be used as a boost converter, but it's not optimized for high-power boost applications. It's more suitable for low-power, low-voltage boost applications.
  • The inductor value for the MC34063ACD depends on the input voltage, output voltage, and output current. A good starting point is to use the formula: L = (Vin - Vout) / (f * ΔI), where f is the switching frequency (around 65 kHz for the MC34063ACD) and ΔI is the peak-to-peak inductor current ripple (around 30% of the output current).
