Working principle

The MAX15000BEUB+T is based on a buck regulator circuit, which is an electronic circuit that can convert a higher voltage to a lower one using simple components. The output voltage is adjustable via an external resistive voltage divider, allowing for fine tuning of the output voltage.At its core, the device includes an N-MOSFET switch and an integrated control circuit for managing the output voltage. The N-MOSFET switch is controlled by either I2C or logic-level signals from the external voltage divider, which work to control the duty cycle of the switch. This duty cycle is used to control the amount of power transferred and thus, the output voltage.The current-mode control ensures that the output voltage remains constant, even if the input voltage or load changes. This is done by constantly monitoring the output current and mechanism, which adjusts the duty cycle accordingly. By using this principle, it is able to keep the output voltage stable in a wide range of conditions.
