MC34063U Frequently Asked Questions (FAQ)
-
The MC34063U can handle a maximum input voltage of 40V, but it's recommended to keep it below 30V for reliable operation.
-
To ensure CCM, the inductor value should be chosen such that the inductor current ripple is less than 30% of the output current. Additionally, the output capacitor should be large enough to filter the output voltage ripple.
-
The internal 2.5V reference voltage is used to regulate the output voltage and provide a stable voltage reference for the internal error amplifier.
-
Yes, the MC34063U can be used as a boost converter, but it's not optimized for high-voltage boost applications. For high-voltage boost applications, it's recommended to use a dedicated boost converter IC.
-
The output voltage of the MC34063U can be calculated using the formula: Vout = (R1/R2) * (Vref - Vsat), where R1 and R2 are the feedback resistors, Vref is the internal reference voltage (2.5V), and Vsat is the saturation voltage of the output transistor (typically around 1V).
