The maximum input voltage that can be applied to the MC34063ABD-TR is 40V, but it's recommended to keep it below 35V for reliable operation.
To ensure stability in 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 voltage is within the recommended range of 2.5V to 40V.
The maximum output current that the MC34063ABD-TR can deliver is 1.5A, but it's recommended to keep it below 1.2A for reliable operation.
The inductor value depends on the input voltage, output voltage, and output current. A general rule of thumb is to choose an inductor with a value between 10uH to 100uH. You can also use the inductor selection guide provided in the datasheet to choose the right value.
The compensation pin (pin 5) is used to compensate for the internal voltage regulator's output voltage. It's recommended to connect a capacitor (typically 10nF to 100nF) between the compensation pin and ground to ensure stable operation.
