The switching frequency is typically in the range of several hundred kilohertz to a few megahertz, allowing for efficient power conversion.

When the input voltage is applied, the internal control circuitry monitors the output voltage through the feedback pin (FB). If the output voltage deviates from the desired value, the control circuit adjusts the duty cycle of the internal switches to maintain a stable output voltage. This process ensures that the load receives a regulated voltage regardless of variations in the input voltage or load conditions.
