Working Principles

The UCC3626PWTRG4 is a voltage mode-controlled synchronous buck controller. It regulates the output voltage by adjusting the duty cycle of the high-side and low-side MOSFETs in the buck converter topology. The feedback voltage from the output is compared with a reference voltage, and the error signal is used to adjust the duty cycle through pulse-width modulation (PWM). This control method ensures stable and accurate output regulation.
