Working Principles

The MAX5035DUSA is a voltage regulator that converts an input voltage within the range of 4.5V to 60V into a regulated output voltage between 0.8V and 55V. It utilizes a switching regulator topology to achieve high efficiency. The device controls the duty cycle of the internal power switch to regulate the output voltage. Feedback from the FB pin is compared to a reference voltage, and the control circuit adjusts the duty cycle accordingly. The SW pin connects to an inductor and capacitor to store and transfer energy during the switching process.
