Working Principles

The UCC24630DBVR is a voltage mode synchronous buck controller. It regulates the output voltage of a power supply by adjusting the duty cycle of the power switch based on feedback from the output voltage. The controller operates by comparing the feedback voltage with a reference voltage and generating a control signal to adjust the power switch accordingly. This control loop ensures that the output voltage remains stable even with variations in input voltage and load conditions.
