Working Principles

The MAX5052BEUA+T is a switching regulator that uses pulse-width modulation (PWM) to regulate the output voltage. It operates by rapidly switching an internal power transistor on and off to maintain the desired output voltage. This switching action allows for efficient power conversion and regulation.

The feedback pin (FB) is used to set the desired output voltage by connecting it to a resistive voltage divider. The error amplifier compares the feedback voltage with a reference voltage and adjusts the duty cycle of the internal power transistor accordingly.
