Working Principles

The MAX14617ETA+T is a step-down DC-DC converter that regulates the input voltage to a lower, adjustable output voltage. It utilizes a synchronous buck topology, where an inductor and a switch (MOSFET) are used to convert the input voltage into a regulated output voltage. The feedback pin (FB) connects to an external resistor divider network to set the desired output voltage. The enable pin (EN) controls the regulator's output voltage, allowing for power management control.
