MC34063ABD-TR Frequently Asked Questions (FAQ)
-
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.
