Working Principles

The RT8026GF is a voltage regulator IC that utilizes a step-down (buck) topology to regulate the input voltage to a desired output voltage level. It employs a pulse-width modulation (PWM) control scheme to achieve high efficiency conversion. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switch to maintain a stable output. The enable pin (EN) allows for easy on/off control of the regulator.
