The MC34063AD can handle a maximum input voltage of 40V, but it's recommended to keep it below 35V for reliable operation.
The inductor value depends on the output voltage, output current, and switching frequency. A good starting point is to use the inductor value calculation formula provided in the datasheet, and then adjust based on the specific application requirements.
The compensation pin is used to stabilize the voltage regulator loop. A capacitor and resistor network is typically connected to this pin to provide the necessary compensation. The values of the capacitor and resistor depend on the specific application and can be calculated using the datasheet's compensation network design guidelines.
The MC34063AD has a maximum operating temperature range of -40°C to 125°C. Ensure good thermal design practices, such as providing adequate heat sinking and airflow, to keep the device within this range.
The minimum ESR required for the output capacitor depends on the output voltage and current. A general guideline is to use an output capacitor with an ESR of less than 1 ohm for most applications.
