Working Principles

The MAX16998AAUA/V+T is a voltage regulator IC that converts an input voltage within the range of 4.5V to 60V into a regulated output voltage between 1.2V and 57V. It utilizes a high-frequency switching technique to efficiently step down the input voltage. The feedback pin (FB) allows the user to set the desired output voltage by connecting an external resistor divider network.

The device operates by controlling the duty cycle of the internal power switch connected to the inductor (LX). This controls the energy transfer from the input to the output, regulating the output voltage. The integrated protection features ensure safe operation by monitoring the current and temperature conditions.
