MC33063ADG4 Frequently Asked Questions (FAQ)

  • The maximum input voltage that the MC33063ADG4 can handle is 40V, but it's recommended to keep it below 35V for reliable operation.

  • To ensure the stability of the output voltage, make sure to use a suitable output capacitor with a low ESR (Equivalent Series Resistance) and a minimum capacitance of 10uF. Also, ensure that the output capacitor is placed close to the IC.

  • The bootstrap capacitor (CBOOT) is used to generate the gate drive voltage for the internal power MOSFET. It's essential to use a capacitor with a minimum value of 10nF and a maximum value of 100nF.

  • The output voltage of the MC33063ADG4 can be calculated using the formula: Vout = (1 + R2/R1) * Vref, where Vref is the internal reference voltage (2.5V) and R1 and R2 are the feedback resistors.

  • The maximum output current that the MC33063ADG4 can deliver is 3A, but it's recommended to keep it below 2.5A for reliable operation.
