Working Principles

The MAX5048BAUT+T is a step-down DC-DC converter that converts a higher input voltage to a lower output voltage. It utilizes integrated power MOSFETs and a control circuit to regulate the output voltage. The switching frequency of 1MHz allows for efficient power conversion while minimizing external component size. The feedback pin (FB) monitors the output voltage and adjusts the duty cycle of the internal switch (SW) to maintain a stable output. The enable pin (EN) controls the converter's operation, allowing for power-saving modes when not in use.
