Working Principles

The MAX8630ZETD15+T is a voltage regulator that takes an input voltage within the range of 2.5V to 5.5V and provides a regulated output voltage of 1.5V. It achieves this by using an internal feedback mechanism that adjusts the duty cycle of an internal switch, ensuring the desired output voltage is maintained.

The regulator operates in a pulse-width modulation (PWM) mode, where the duty cycle of the internal switch is varied to regulate the output voltage. The FB pin connects to an external resistor divider network, allowing the user to set the desired output voltage.
