Working Principles

The MAX5058AUI+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 0.6V and 55V. It achieves high efficiency by utilizing a synchronous buck topology. The IC operates by controlling the duty cycle of the internal power switches to maintain the desired output voltage.

The feedback pin (FB) allows the user to set the desired output voltage by connecting an external resistor divider network. The soft-start/ tracking pin (SS/TR) enables controlled startup and can be used for sequencing multiple regulators. The compensation pin (COMP) provides stability to the control loop by adjusting the frequency response.
